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
