COMBINE

        [BUNDLES\]COMBINE OutCube CODE In1 In2 [Off] [/FACTOR A1 A2]
      [/THRESHOLD T1 T2] [/BLANKING Bval] [/RELATIVE]

      or

    [BUNDLES\]COMBINE OutCube = [A1*]In1 Oper [A2*]In2 [Off]
      [/THRESHOLD T1 T2] [/BLANKING Bval] [/RELATIVE]

    This  is a superset of the MAP_COMBINE command, that automatically resamples
    and reproject the In1 and/or In2 data sets so that they match spatially (ac-
    cording to In1, in Absolute positions or only in  Offsets  if  /RELATIVE  is
    preseent) and spectrally (when both are data cubes).

      See  HELP  MAP_COMBINE  for  details  on  the  combination codes, factors,
    thresholds and blanking. In the second "natural" form, Oper can  be  any  of
    the  recognized  values  for  CODE, or the classical operators +, -, * and |
    (the / would conflict with the option separator).

    Cube, In1 and In2 are names of files or SIC Image  variables,  depending  on
    whether a dot (.) is present in them or not.
