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 pre-
       fix.

REFERENCES

       description  can be found in Astronomy & Astrophysics Sup-
       plement Series 44 (1981), page 363.
