VPhot does not recognise calibration process from ASTAP

Please can anyone advise. Trying to get a time series of a flare star.
I use ASTAP for calibrating my CMOS images prior to uploading to VPhot for photometry.
I have recently amassed a time series set of obs on AD Leo a flare star, looking for events at a 10s time resolution.
VPhot does not recognise that they have been calibrated.
I used align and calibrate procedure in ASTAP.

Kevin:

VPhot is looking for a specific fits header (CALSTAT=BDF) to report calibration. HOWEVER, just ignore the fact that the Cal button in your image list is red. You know that your images are calibrated. There is probably a HISTORY header installed by ASTAP?

Just proceed with your photometry as normal.

Thanks Ken,
Very reassuring. I’ll proceed. I will check the header.
