REGISTER/ROMAFOT

REGISTER/ROMAFOT int_tab reg_tab [wnd_opt] [obj_opt]

This command creates a table with the results of the analysis. However, all the photometric information obtained from the frame as the absolute quantities (magnitudes, colour equations etc.) still have to be derived. In this output table every object occupies one row and the data are stored according the Table 5.2.

 

#1 :IDENT Identification

#2 :X Physical X-coordinate

#3 :Y Physical Y-coordinate

#4 :INT central pixel intensity resulted from the fit

#5 :LOC_BG Local sky background; see text

#6 :MAG1 Aperture magnitude no.1; see text

#7 :MAG2 Aperture magnitude no.2; see text

#8 :MAG3 Aperture magnitude no.3; see text

#9 :MAG_CNV Instrumental magnitude; see text

#10 :SIGMA Sigma of fit function (if not fixed by the user)

#11 :BETA Parameter of the Moffat fit function

#12 :SIQ Semi interquartle resulting from the fit

#13 :CHI_SQ resulting from the fit

The magnitudes MAG1, MAG2 and MAG3 (e.g. U, B and V) are accepted by the commands FIND/ROMAFOT or SELECT/ROMAFOT and are necessary for calibration. In case of program stars (search made with SEARCH/ROMAFOT), these columns are filled with zeros.

The instrumental magnitude MAG_CNV is calculated as , where VOL is the integral over the elementary surface to fit the star, calculated from to . In case of linear data this is expected to differ from the magnitude by a constant.
