CHECK/ROMAFOT cat_tab reg_tab err_mag
This command can give an answer to the questions what fraction of artificial frame has been recovered, and to what extent photometry is affected by crowding of frames?
This is accomplished by comparing the instrumental magnitudes and positions (recorded in the catalogue file generated by ADDSTAR/ROMAFOT) with that derived through the complete procedure and recorded in the output table. The results are arranged in the form of a histogram for the sake of a synthetical understanding. In addition, CHECK/ROMAFOT modifies in the catalogue table the positions setting flag to 1 for the objects that have been recovered, while this flag remains set to 0 for the undetected ones.
