Name
       iofits - FITS data format conversion (pixel depth)

Synopsis
       iofits [options] <in_fits> <out_fits> <depth>

Description
       iofits  converts  FITS files of any pixel depth to another
       pixel depth (bits per pixel). Depth is  given  as  in  the
       FITS norm :


       *      8 bits per pixel, unsigned.

       *      16 bits per pixel, signed

       *      32 bits per pixel, signed

       *      -32 IEEE floating point

       *      -64 IEEE double precision floating point

Options
       -v     Verbose mode.

       -M megs
              Memory  handling. To avoid saturate memory for huge
              cubes, this parameter specifies the maximum  amount
              of memory to use before swapping data to disk.  The
              amount is given in Megabytes.   (1Meg  =  1,048,576
              Bytes) The process time is then considerably slowed
              down.  Default value is 50 megs.

Files
       Input/output files shall all comply with FITS format.

       The original FITS header  of the input FITS file  is  con-
       served  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, together with  the
       command line which was used to generate the file.

Bugs
       In  general,  decreasing  the resolution in number of bits
       per pixel  almost  always  means  loss  of  precision.  No
       rescaling is done on the data, use this command with care!
