OPERATORS
Listed in order of decreasing precedence:
( expr ) Force precedence. ! expr True if expr is false. _not expr Same as ! expr. expr1 expr2 And (implied); expr2 is not evaluated if expr1 is false. expr1 _a expr2 Same as expr1 expr2. expr1 _and expr2 Same as expr1 expr2. expr1 _o expr2 Or; expr2 is not evaluated if expr1 is true. expr1 _or expr2 Same as expr1 _o expr2. expr1, expr2 List; both expr1 and expr2 are always evaluated. The value of expr1 is discarded; the value of the list is the value of expr2.

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.
