BUG: 	The normalized reference spectrum was being copied from the object
	spectrum when the image names were the same as a form of optimization.
	This could fail in cases where the 'n' key was used to move through
	a list to get the next object and the object spectrum was previously
	rebinned at a different dispersion causing artificial shifts in 
	the data.  The code was modified to always compute a normalization
	to avoid this in all cases.  Workarounds include rebinning all
	spectra to a common dispersion or setting the 'rebin' param to be
	'object'.

STATUS:	Fixed in versions after V2.10.4p2.
