Name
       catcube - cube/image concatenation to one cube

Synopsis
       catcube [options] [-o output] <cube1> [cube2] ... [cube n]

Description
       catcube creates an output cube that is sum on  the  z-axis
       of  all  other  cubes  given  on  command line in order of
       appearance from left to right. e.g.
       catcube -o outcube cube.001 cube.002 image.001 cube.003
       will create an output cube `outcube' with planes  consist-
       ing  of  planes  cube.001  first, then planes of cube.002,
       then image.001, then cube.003.  All planes shall have  the
       same  size  (width, height). The pixel depth of the output
       cube is the most restrictive, i.e. the one which needs the
       highest amount of bits.  catcube accepts jokers on command
       line :
       > catcube -o output.fits ADO*.fits

       The default output name is `cat.fits'. The -o  option  may
       be  specified  anywhere  on the command line. Example: the
       following lines are strictly equivalent:

       catcube f0001 f0002 -o output.fits f003 f004

       catcube -o output.fits f0001 f0002 f003 f004

       catcube f0001 f0002 f003 f004 -o output.fits

Files
       Input files shall all comply with FITS format Output  file
       pixel type is the highest input pixel type encountered.

       The  original FITS header  of the first given FITS file on
       command line is conserved along, except for the  following
       keywords:  NAXIS, NAXISn, BITPIX, BSCALE, BZERO, which are
       related to the newly created file.

       HISTORY keywords are appended to the FITS header to  indi-
       cate the eclipse process modifications.
