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 image 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 -scan-
       max 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 Astronomy & Astrophysics Sup-
       plement Series 44 (1981), page 363.
