NAME
       fitstopnm - convert a FITS file into a portable anymap

SYNOPSIS
       fitstopnm [-image N] [-noraw] [-scanmax] [-printmax] [-min f] [-max f] [FITSfile]

DESCRIPTION
       Reads a FITS file as input.  Produces a portable pixmap if the FITS file consists of 3 im-
       age planes (NAXIS = 3 and NAXIS3 = 3), a portable graymap if the FITS file consists  of  2
       image  planes (NAXIS = 2), or whenever the -image flag is specified.  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.

       Flags  -min  and -max can be used to override the min and max values as read from the FITS
       header or the image data if no DATAMIN and DATAMAX keywords are found.  Flag -scanmax  can
       be  used  to force the program to scan the data even when DATAMIN and DATAMAX are found in
       the header. If -printmax is specified, the program will just print the min and max  values
       and  quit.   Flag  -noraw  can  be  used to force the program to produce an ASCII portable
       anymap.

       The program will tell what kind of anymap is writing.  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 As-
