NAME
     iofits - FITS data format conversion (pixel depth)

SYNOPSIS
     iofits [options]   

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 indicate
     the eclipse process modifications, together with the command
     line which was used to generate the file.

SEE ALSO
     average, arcube, filt, deadpix, cleandead

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!
