SPECTRUM /SUM

        [GREG3\]SPECTRUM OutSpec InCube [Mask] /SUM
      [/CORNER Imin Imax Jmin Jmax] [/PLANE First Last]

      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.
