Question: Does Vphot attempt to plate solve images even though were already solved when they were uploaded?

Plate solving

Hi Geoff:

Vphot looks at the headers in each image to determine if it has already been plate solved, i.e., there are some CR  and TR headers present. If so, it skips the plate-solving step but it does put a history header into the headers. Sometimes this gives the impression that it did another plate-solving but that is not the case.

HTH, Ken
