CHECK/ROMAFOT                                                    26-AUG-1989 RHW

CHECK/ROMAFOT cat_tab reg_tab err_mag
	examine number of artificial stars recovered and check the accuracy
\us\pu
Purpose:      Examine the number of artificial stars recovered and check
              their photometric accuracy
\up\sy
Syntax:       CHECK/ROMAFOT cat_tab reg_tab err_mag
\ys\pa
              cat_tab = catalogue table containing positions and instrumental
                        magnitudes of artificial objects. This file is
                        created by ADDSTAR/ROMAFOT; no default name.
\ap\pa
              reg_tab = registration table. It contains photometry on the
                        artificial image frame made using the reduced
                        intermediate file created by FCLEAN/ROMAFOT. No default.
\ap\pa
              err_mag = limit error in instrumental magnitude. As an artificial
                        object may fall on a pre-existing object, the
                        simple correspondence of positions does not guarantee
                        unambiguous identification (positions must differ
                        less than 2 pixel to define a coincidence). No default.
\ap\no
Note:         none

Examples:
\ex
              CHECK/ROMAFOT GCLUCAT GCLTAB 0.3
              Examine catalogue table GCLUCAT and check how many objects present
              here are found in the registration table GCLTAB. Two objects are 
              coincident when their positions differ less than 2 pixel and 
              their instrumental magnitude differ less than 0.3
