BUG:	If no arc image or standard star image is specified an error such as

	ERROR on line 103: OPEN: File does not exist (tmp$iraf1665j)
	    doecslit ()

	will appear.  This is true even if one is not dispersion correcting
	or standard star fluxing.  Thus, even if dispcor=no or fluxcal=no
	you must put a placeholder image name in the arcs and standard
	parameters.

STATUS:	Fixed in V2.10.3 and later such that not specifying arc and standard
	star images is ok if not dispersion or flux calibrating.
