| Information concerning all isophotal photometric calibrations in the SSA |
| Over the course of several implementations of the SuperCOSMOS Sky Survey, several revised calibrations of the isophotal photometry have been done. This table stores the calibration version numbers, start and end dates relevant for those calibrations, and a short description for each version of the isophotal photometry scale (note that this is not applicable to point-like sources brighter than around 3 magnitudes above the respective plate limits; in any case, the profile magnitude scale should be used for point sources). |
