Hi,

Is it possible to add a line in the FITS Header after a calibration is done.  
CALSTAT = BDF

I know we can add this line manually.  What I suggest is to add automatically this line when we do the calibration (CCD Data Processor).

This line is recommended in VPhot when images are uploaded in order to recognize that the calibration is done.  

So CALSTAT is to display calibration status (combinations of B, D and F where B is bias, D is dark, F is flat fielded), or BIASSUB/DARKSUB/FLATTED to display calibration status.  

So if only dark and flat are applied, CALSTAT=DF, if bias,dark,flat applied... CALSTAT=BDF etc...

thanks
Serge
