BUG:	When the input spectra are in equispec format (all spectra with the
	same linear dispersion relation) and there are aperture numbers
	which are greater than the number of image lines then the error
	'WFMSPEC: Coordinate out of bounds' may occur.  Such a situation
	will only occur when resampling an an already dispersion corrected set
	of spectra and not when using an IDENTIFY or ECIDENTIFY database.
	This is due to a logical error in the code concerning mapping of
	aperture numbers to line numbers.  The workarounds are to use
	SARITH if simply extracting a region, extract the spectra to
	onedspec format with SCOPY, or change the WCS with:

		cl> hedit  cd2_2,cdelt2 1000 update+
		cl> hedit  crpix2 1 add+

STATUS:	Fixed for the next release.
