AIRMASS CALC  is a very simple program, or if you like quite a modern one, a tool which does only one thing: it computes Airmass and Scintillation which satisfies different criteria.

AIRMASS CALC can rewrite the report AAVSO with adding the airmass in the correct column.

Many thanks to Arne Henden (AAVSO Director) and Aaron Price (Technical Assistant, Technology) for their help and encouragement.

        Date
        Hour
        JD (Julian day)
        Airmass
        Scintillation

The second tab displays a graphic with the value of airmass in function of the hours
        

                                 


Rewriting

A new window is displayed, you have two choices with two format of files

- Old format

- New format (or extended format)

Choose your file


the soft controls the validity of the file 

The original file is not over written


A new file is created, an extension is added : 

Original Name + "-Airmass-"+ date of rewriting (yyyymmdd).txt
