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
