fitstopgm(1)            UNIX System V(20 September 89)             fitstopgm(1)


NAME
      fitstopgm - convert a FITS file into a portable graymap

SYNOPSIS
      fitstopgm [-image N] [FITSfile]

DESCRIPTION
      Reads a FITS file as input.  Produces a portable graymap as output.  The
      results may need to be flipped top for bottom; if so, just pipe the
      output through pnmflip -tb.

OPTIONS
      The -image option is for FITS files with three axes.  The assumption is
      that the third axis is for multiple images, and this option lets you
      select which one you want.

      All flags can be abbreviated to their shortest unique prefix.

REFERENCES
      FITS stands for Flexible Image Transport System.  A full description can
      be found in Astronomy & Astrophysics Supplement Series 44 (1981), page
