Output Table

The output table contains the results and therefore it is necessary to know in what columns different quantities are stored. Table 4.1 gives a list of columns together with their numbers and labels. Column :CLASS is filled with data by the CLASSIFY command.

#4 :MAG_CNV Convolved magnitude. Applicable to stars.

#5 :MAG_AP_1 Aperture magnitude no.1.

#6 :MAG_AP_2 Aperture magnitude no.2.

#7 :REL_GRAD Relative gradient. Should be 0.0 for stars.

#8 :SIGMA_GR Sigma of profile deviations from P.S.F.

#9 :BG Local sky background.

#10 :INT Average intensity of 9 central pixels.

#11 :RADIUS_1 Intensity weighted average radius in pixels.

#12 :RADIUS_2 Intensity weighted average root square radius in pixels.
