So the image it outputs, is that a calibrated image? Is it possible to tell?
What does the software do to the original uncalibrated lights?
Hi Kevin,
ASTAP does nothing to your uncalibrated lights and it creates calibrated copies with “_cal” on the end of the file names.
If you look at the FITS headers of the calibrated files, you will see something as shown below towards the end of the header. In my test I only selected my master dark and master flat files and you can see resulting CALSTAT = ‘DF’. Also the COMMENT 1 field indicates it was calibrated by ASTAP.
What do you see in the CALSTAT field when you use your flat-darks?
Cheers
Ian.
COMMENT 1 Calibrated by ASTAP. http://www.hnsky.org
PEDESTAL= 5.000000000000E+002 / Value added during calibration or stacking
CALSTAT = ‘DF’
DARK_CNT= 1 / Darks used for luminance.
FLAT_CNT= 1 / Flats used for luminance.
