Spatial mode   : Modelled datum
Notes          : From new raw data
Qualifiers     : SDSS flags
                 CANONICAL_CENTER - used canonical, not local, center
                 NOPETRO - no Petrosian radius could be determined
                 NOPETRO_BIG - Petrosian radius is larger than extracted radial profile
                 BAD_RADIAL - some low S/N radial points
                 ELLIPFAINT - no isophotal fits performed
                 AMOMENT_FAINT - too faint for adaptive moments
