I recently noticed, that when taking flats and darks (maybe bias too, but haven’t testet), the FITS header does not contain the keys EXPOSURE and EXPTIME as the light frames do. I hereby request to add them. Btw: it does not matter if the calibration frames are taken in Live or Autorun – the results are the same.
This would help the Weighted Batch Preprocessing Script in PixInsight to automatically read out the exposure of the subs to group them properly.
Kind regards,
Olli
