Notes          : From new raw data
Qualifiers     : SDSS flags
                 CANONICAL_CENTER - used canonical, not local, center
                 NOPETRO - no Petrosian radius could be determined
                 PETROFAINT - Petrosian radius measured at very low surface brightness
                 ELLIPFAINT - no isophotal fits performed
                 AMOMENT_FAINT - too faint for adaptive moments
