By the way, we are finalising a new version of our software, to be called, presumably v3.8. We have included some suggestions from users, in particular Jean-Francois. The improvements are small but useful (see below). If you have some additional ideas for improvements or new features, post them here.   1. Improved spectral line fitting for, in particular, Calcium. 2. Improved ellipse fit that does not get confused by sunspots. 3. An additional CLI command to cancel ellipse correction (currently possible through the GUI by entering 1, 0) 4. Improvement in transversalium correction to reduce "shadows" created by very bright features (e.g. Calcium) or very dark features (e.g. sunspots).
