I'm new to VPHOT and am working through the learning curve...
VPHOT has acknowledged that I have successfully uploaded a time series of images that have been plate-solved. That indicator is green. The Cal indicator for all the images are red. Before I uploaded these images I did perform a calibration (Bias, Darks and Flats). I've checked and found that the FITS header shows this in the history of the image. What have I done wrong or still need to do?
I would appreciate any help!
