Copyright

All is permitted as long as you comply with the law

This site is attached to commercial works which content is sometimes available on this web. In order to respect the copyrights associated to these works, you are not allowed to publish my documents, to copy, to modify or to translate them, without first written consent of the author or purchasing a license. This includes but is not limited to newsgroups, personal and non-profit websites.

You have also to ask for permission to the individual authors whose images are released on this site. The webmaster can only grant it to you for his personal works.

Contrary to popular opinion, altering an image or inserting a link on your website to this one does not free you from copyright infringement liability.

Images displayed on the site may be digitally marked for tracking purposes.

How work copyrights?

For more information about copyrights read these commentaries where I explain what are your rights and duties in order to respect the regulation which objective is to protect the authors' interests.

For short, the reproduction of documents published on this website are ruled by the Berne Convention on Copyright and are reserved (see below) due to the fact that they are protected by three copyrights : the one of the author and two from the publishing house Aegeus.

Unless you read the contrary, due to different claims for plagarism addressed to several amateurs, I do not more grant permission to copy or wrap my documents to members or moderators of newsgroups (forums), responsibles of blogs, RSS(1) and other website. This decision prevails on the one from the publishing house.

Any use, including the translation of one of my documents without credit and without written permission or optional paiment of a fee will be considered as a plagiarism.

However, if needed we can find a mutual arrangement. See the other questions, and in case of any doubt contact me by email *before* any use in explaining me the frame of your action, and providing me the URL of your site for evaluation. Due to the many abuses, no permission will be granted if the concerned website cannot be first accessed and evaluated. The possible granted permission is nominative, non transferable and is never irrevocable.

Can I insert a link to your website?

Due to the copyrights attached to this website, the copy of my menus or directory of hyperlinks (1001 links) as well as the link to my pages by inserting a frame (sometimes called the wrapping technique) on your web is denied. Only a simple hyperlink to my pages in full screen (not in a frame) is accepted.

However, I grant the right to insert a link to my webiste as long as there is no harm for my interests or the one of the house edition. I always accept a link to my website when it is to constitute a directory, to refer to one of my documents and as long as the criticism is constructive. I only ask you to prevent me by email before creating the link if you do such a reference so that I can judge the interest of this publicity and optionally to ensure a follow up of sites supporting my project.

Can I publish your images on my non-profit website?

Reproduction rights of images released on this website are reserved. If you want to publish an image that does not belong to me but released on this website, you have to ask directly the permission to the concerned author or his representative. In this purpose, an hyperlink to the source of document is usually displayed below each illustration.

Each image or text published on this website received the author's grant in writing or implicitly, completed with a link to the owner's website. If you are interested in using some of these documents, know that some usages (e.g. renderings made by illustrators or pictures collected by an agency, a photographer, an editor or a museum) could be invoiced. In this case you have to find a mutual arrangement with the owner of the document.

I do not allow the use of my images in a framework contrary to proprieties, racist or encouraging violence.

I do not allow that my images are published as banner (or frame) on a website and thus included as header and repeated in several pages without condition. In this case or if I denied to give you a free copy, and for any commercial use, see the next question.

I do not allow the copy of my images on newsgroups (forums), blogs or RSS(1). On the other hand, I tolerate the publishing of a link to the concerned page of my website at the condition that it is a constructive criticism.

Illustrations being protected by copyrights, I do not allow that original images are displayed in full size on your website (e.g. by download, copy, using an [img] command or a direct link) without written permission, without credit line or without paiment of a fee depending on the case. In case of agreement, the illustration must be a significative reduction of the original format (e.g. 150 pixels high maximum) completed with all required mentions.

In all other cases, if you want to use some of my images on your website, and not as a banner repeating on several pages, I willingly accept that amateurs, students (scholar work), scientists or any non profit association uses my illustrations (Alien Worlds, Terragen, Illustrations, Voyages et tourisme, Infrared World). Contact me by email *before* using any image to explain me the purpose of your publication. If case of agreement, I ask you to include the source of your information in your work, my name and, if possible, the website address (URL), either in clear or inserting a link under my name.

Can I publish your images in my non-profit magazine?

Reproduction rights of images released on this website are reserved. If you want to publish an image that does not belong to me but released on this website, you have to ask directly the permission to the concerned author or his representative. In this purpose, an hyperlink to the source of document is usually displayed below each illustration.

If images are published in a magazine sent or sold by subscription to members of an association or a company and which internal pages display more than 5 publicity inserts, I consider this as a commercial action. In this case, see the next question.

In all other cases, but under conditions, I willingly accept that non-profit associations use my illustrations (Alien Worlds, Terragen, Illustrations, Voyages et tourisme, Infrared World) in their magazine. Contact me by email *before* using any image to explain me the purpose of your publication. 

In case of agreement, the image can be inverted or cropped but cannot be modified. Only the gamma can be adjusted in a margin of 25%. The signature cannot be removed (excepted for publishing on paper. In this case, if the signature is cropped, my name must be added close to the image). For lack of this data, it will be considered as a plagiarism. I ask you to include the source of your information in your magazine, my name and, if possible, the website address (URL). At last, send me an examplary of the work in which the picture was published.

Can I use your images to create a poster for our non-profit association ?

I usually accept to share my works with non-profit organizations dealing with sciences or some hobbies developed on this site. To prevent any copyright infringement contact me by email *before* using any image to explain me the purpose of your poster or send me a mockup of your project. 

In case of agreement, the image can be inverted or cropped but cannot be modified. Only the gamma can be adjusted in a margin of 25%. The signature cannot be removed. If it is cropped, my name must be added close to the image. For lack of this data, it will be considered as a plagiarism. At last, send me an examplary of the poster.

In all other cases, I ask you a fee (see the next question).

Can I publish your articles on my site or in a non-profit magazine?

Reproduction rights of articles or comments released on this website are reserved. I do not allow the copy or hard-link to my articles on blogs, RSS(1) or newsgroups (forums).

On the other hand, I tolerate the publishing of a simple hyperlink to the concerned page and in full screen (not in a frame) on my website at the condition that it is a constructive criticism.

In all other cases, articles published on this site can be used freely by anyone at educational purposes (scholar works) or by a non profit association under conditions; in particular extracts or quotations must be limited to 1000 characters maximum or one paragraph.

I am favorable to negociate an arrangement for educational works within the school framework (manual, thesis, etc). Contact me by email *before* publishing in describing the project and the kind of publication planned (institution, author, objective, audience, support, etc).

In all cases, I ask you to include the source of your information in your work, my name and, if possible, the website address (URL), either in clear or inserting a link under my name. If the name is not listed, it will be considered as a plagiarism. At last, if relevant, send me an examplary of the magazine, book or CD in which the picture was published. For any other use, you have to buy the concerned article (see the next question).

Purchases and Licenses

Do you have an US federal tax ID number (w8 form) ?

I do not have an US federal tax ID number. Therefore I do not sale my artworks to US companies using a w8 form (as in this case the US government can take up to 30% of the check). However, I hope that we can find a mutual agreement with your company, e.g. wiring the payment through one of your bureau outside the U.S. so that you can benefit of my artworks.

Can I buy prints of your artworks ?

Quality prints of my works (Alien Worlds, Terragen, Illustrations, Voyages et tourisme, Infrared World) are available at low cost. Pictures and renderings are printed on Kodak Premium glossy or semi-glossy paper.

See the next question for the license paiment.

Contact me by email for using my images in an advertising, to illustrate a calendar or to publish them on another media.

New-commissioned renderings require some delay or some preparation. Contact me by email for more details.

Explanations:

If you are interested in using my illustrations, send me an email *before* any use in describing the kind of publication, the printing, the name of the image and the electronic format that you want.

The license price is unique and is worth for the illustration of any part of a page of your media (e.g. from a quarter page to a double page of a magazine). 

The license price is worth for a single copy in electronic format, and without exclusivity of right.

The image will be sent you at receipt of your paiment, usually within 24 hours. A delay of paiment is granted to editors.

Images smaller than 2 MB are sent by email. If your mailbox rejects them, images will be put at you disposal on my website during 7 days so that you could easily download them.

Images are usually provided in electronic JPEG format up to the resolution 2048 x 1536 pixels (some in 4700 x 3130 pixels, other sizes or formats on request), 24-bit True color, 300 dpi, excepted other mention (for Artworks). Most images are associated to color spaces (Adobe RGB, see this French page).

The JPEG file size if usually between 1.5-4 MB and its quality satisfies to requirements of any publication (remember that a uncompressed TIFF file needs 300 to 700 MB of disk space).

For my pictures (Voyages et tourisme, Infrared World and some Twilights), the same conditions apply, excepted that images are available in JPEG format only, and come in various formats from 1024 x 768 to 4700 x 3130 pixels, 24-bit True color, 300 dpi. Some digital images are 10% shorter than a 35 mm image (e.g. 50x63 cm instead of 50x70 cm).

The image can be inverted or cropped but cannot be modified. Only the gamma can be adjusted in a margin of 25%. The signature cannot be removed (excepted for publishing on paper. In this case, if the signature was cropped, my name must be added close to the image) For lack of this data, it will be considered as a plagiarism. I ask you to include the source of the image in your work, the copyright line and, if possible, the website address (URL), either in clear or inserting a link under my name. At last, if relevant, send me an examplary of the work in which the picture was published.

How to proceed to buy your articles?

All articles associated with the publication of my book about quantum physics (La Physique quantique at Aegeus) cannot be reproduced without my written permission and the one of the editor.

The license price for reprinting or adapting one of my articles depend on the support and visibility :

Support

Fee

Book at educational purpose (museum, etc) :

50 €

Website :

200 €

Newspaper, Magazine, Periodical :

250 €

Book or CD :

300 €

Adaptation for radio and TV :

400 €

Add 20 € to cover bank charges and administration.

These fees are worth whatever the size of the document, the printing, and without exclusivity of right. See this question about the way to pay the license.

The original article will not be removed from my website but an additional comment will be added about your publication (with a possible link to your website).

If the article includes personal illustrations, this price includes these images as well (my own images only). They will be joined to the document in the highest resolution available. At last, if relevant, send me an examplary of the magazine, book or CD in which the article was published.

Any explicit use requires the paiment of a license and the mention of my name and, if possible, my web site URL. At last, send me an examplary of the work in which the article was published.

In the case of a radio or television broadcast, prior any use send me a mockup of the broadcast (PDF, Word, Excel, VHS or DVD format). Contact me par email for more details.

How to pay the license or the print?

I don't have a PayPal account. For any document requiring the paiment of a license (reproduction right) and for prints, I ask you to pay in euros and to wire the money directly to my bank account in Luxembourg. It is cheaper for both parties to transfert the money directly between bank accounts. It is also very fast (1 or 2 days). An invoice will be sent you. Contact me by email for detail.

You can also send me an international money order (via the post office) addressed to my name and makes out in euros.

You can send me at your risks banknotes (euros) in a opaque envelope by postal mail. Up to now mails have always reached their destinee.

At last, if you want to send me a bank cheque by postal mail (concern mainly US citizens), I am sorry to ask you to add 30 euros to the set price. Unfortunately, using this latter way charges are much more expensives compared to a simple bank transfert. The delay of paiment is also longer (rekon about 1 month before I could send you the document!).

May I buy your book about Quantum Physics directly in sending you a cheque or an email?

I have no stock at home ! All orders must be transmitted to my editor Aegeus by email who manage all commercial concerns. Mention in your mail that you discovered the book thanks to my website. You will benefit of 5% discount.

Miscellaneous questions

How to work with NASA or ESA?

You can be official or under temporary contract. Apply directly on NASA website or contact a near university or an engineering company working in collaboration with NASA. The same procedure applies to ESA. Contact also your national ministry in charge of new technologies, economy or the federal representative of enterprises. Here are two useful links at ESA : How to become an astronaut ?, Benefits for Europe.

I found a possible meteorite. How to certify its origin?

If you suspect have found a meteorite, do contact your nearest public observatory, national science museum or planetarium. They will explain you actions to take. In France do contact SAF's Commission Mιtιores et Mιtιorites, in Canada do contact MIAC and in the U.S.A the Center for Meteorites Studies or the Smithsonian - National Museum of Natural History, Division of Meteorites. Excepted amateur societies, this estimation is usually invoiced.

Are your articles available in Word or PDF format?

Currently articles are only available in HTML, sometimes formatted for printers (in this case a logo showing a printer is displayed on top of the article. They are a handful only). Other documents (tables, graphs, etc) are available in other formats (PDF, XLS, ZIP) in both astronomy and amateur radio download sections.

When I print your pages, there are truncated at right. How to fix this problem?

To correctly print HTML pages, use either a performing browser like FireFox or copy and paste each page (the all "white" page, including pictures but without menus) in a Word document, then justify it (align the text at left and right) and check the page break. No other formatting is required. The document is now ready for printing.

How to get more information about your biography?

See the few information published in my biography. You will understand that I do want to share private information on the Internet.

Employers, scientists or amateurs wishing to meet me are asked to contact me by email  to arrange an appointment.

How to find on the Internet scientific papers that you have listed?

Once published, most articles are only available by subscription to the concerned magazine. These magazines are usually available in large public libraries where you will be free to consult or to photocopy them. Preprints, i.e. papers not published yet and not approved by referees, are usually accessible via Goggle scholar or directly on ArXiv.

If these sources are of no use, contact directly one of the authors of the concerned paper. Often his or her email address is displayed on the website of the university or the company listed on top of the paper.

At last, you can ask your question on any scientific newsgroup dedicated to this theme.

Do you have plans to design a telescope, a sundial, a HF or VHF antenna or weather equipment?

I have no more plans. On the other hand, amateur associations and manufacturers provide sometimes construction blueprints or diagrams to the public. Books have also been published on these subjects. First of all, check my 1001 Links (at Books, Clubs & Amateur Associations, Images, Manufacturers and dealers) and newsgroups.

How to buy a scope or a transceiver?

I am neither a shop or a saleman and I do not sell any kind of material, and thus do not ask me for prices or to order any kind of product. Instead, check my 1001 Links at "Manufacturers and dealers".

However, I can give you advice. In addition, you will find technical reviews of astronomy equipment in my French and English pages and reviews of amateur radio equipment in these pages.

Another question?

Look first for the institute, the company, the club or the amateur in my 1001 links. Optionally, make a search on my website using keywords. Without answer, check on the Internet using Google. A query on english-written websites will always provide you more information than any foreign request. It is a very powerful and performing tool that will provide answers to most of your questions in a few mouse clics. Check also newsgroups (via Google Groups or using your mail system, this latter being updated much quickly).

I hope have answered to some of your questions.

Remarks

Blog : journal or diary kept online. They are often updated, like news websites. Their update is usually not established via FTP but using a complex managing system, and they must remain online during servicing (sometimes with a password). They can become very huge like classic Internet websites. They can be used for marketing purposes and drain a large audience. More than one responsibles of blogs doesn't respecting the regulation on copyrights, I decided with regret to not allow them to reproduce my documents or the one of people supporting my project.

RSS : Really Simple Syndication, is also a fast way to feed Internet with information.

NB. All illustrations displayed in this article are published in the frame of fair use rules or received the author's explicit permission. In the first case (but in the second as well) the author can always request the removal of the document.
