75Photcode Suffixes
76----------------------
77(photcode):inst – instrumental magnitude; -2.5*log(counts)
78(photcode):sys – inst magnitude adjusted by the chosen mag system zeropoint
79(photcode):cal – sys magnitude adjusted by the chosen color correction
80(photcode):rel – cal magnitude adjusted by a zeropoint offset due to sky varriation (default value for mextract)
81(photcode):ave - <rel mag> (default value for avextract)
82(photcode):err – (for mextract) the measurement error for rel magnitude, (for avextract) the error of the ave magnitude
83(photcode):chisq – the chi-square of the photometry fit (valid only for avextract)
84(photcode):ref – the ave magnitude value for a given photometric system ref (such as PS, SDSS, 2MASS, etc.)
