      output maps and the standard reference maps.

      DIFF is either the max difference between the images or
      the RMS difference.
      (LOG is the Base 10 Logarithm; 1/LOG(2) = 3.3219)
      MAPDIF(1-2,.) => peak, mean bits
      MAPDIF(3-5,.) => dx,dy,dT
      MAPDIF(.,1-8) => UVMAP, UVBEAM, APCLN, APRES,
                       MXMAP, MXBEAM, MXCLN, IVTESS
