# Table columns in Photometric Catalogs
NUMBER			Object ID Number
X_IMAGE			Object X-Position (in pixel)
Y_IMAGE			Object Y-Position (in pixel)
ALPHA_J2000		Object Right Ascension (J2000)
DELTA_J2000		Object Declination (J2000)
MAG_AUTO_[z/i/r]	SExtractor Kron-like elliptical aperture magnitude for z-, i-, r-mosaic
MAGERR_AUTO_[z/i/r]	SExtractor RMS error for MAG_AUTO for z-, i-, r-mosaic
MAG_AP_CORR_[z/i/r]	SExtractor Fixed aperture (D = 7 pixel = 1.6 arcsec) magnitude for z-, i-, r-mosaic
			The MAG_AP_CORR includes an aperture correction to compensate for seeing variations 
MAGERR_AP_[z/i/r]	SExtractor RMS error for MAG_APER for z-, i-, r-mosaic
FWHM_IMAGE_z		Object FWHM (in pixel) assuming a Gaussian profile
ELLIPTICITY_z		Object Ellipticity (1-B/A)
FLAGS_[z/i/r]		SExtractor Flags for z-, i-, r-mosaic
CLASS_STAR_[z/i/r]	SExtractor Star(=1)/Galaxy(=0) classifier for z-, i-, r-mosaic
UL_iband		Boolean flag for upper limit for i-band fixed aperture magnitude (=1 if MAG_AP_CORR_i>26.5)
UL_rband		Boolean flag for upper limit for i-band fixed aperture magnitude (=1 if MAG_AP_CORR_r>27.2)
