Excalibrator: RGB Image calibration

Post by AstroBernd » 17 May 2021, 19:16

Any experience by users with the above program from B. Franke? http://bf-astro.com/eXcalibrator/excalibrator.htm. It was recently reviewed in a german astronomy journal.
It takes the plate solved image and determines the coefficients between the 3 color channels from the star colors in catalogs. It requires separate fits files for each color channel.
Anybody having already done this from within AA with a script or macro to prepare the files for it? Could it be worth a plug-in?
Looking forward to your answers and opinions
Bernd
