bool	project			# Combine across the highest dimension?
real	blank			# Blank value
pointer	expkeyword		# Exposure time keyword
pointer	statsec			# Statistics section

pointer	gain			# CCD gain
pointer	snoise			# CCD sensitivity noise
real	lthresh			# Low threshold
real	hthresh			# High threshold
int	nkeep			# Minimum to keep
real	lsigma			# Low sigma cutoff
real	hsigma			# High sigma cutoff
real	pclip			# Number or fraction of pixels from median
