          Indicates that we are computing an integrated spectrum, not extracting
          a spectrum from the default Greg data cube. Blanked pixels
          are treated as zeros. The result corresponds to the integral
          of the signal over the valid area (sum of values times the
          pixel size in user units).

          /SUM is typically used to compute integrated flux from Jy/Beam
          units.
