BUG:	This is not exactly a bug but a limitation.  The Voigt profile fitting
	requires a minimum value for the width parameters to avoid
	numerical problems.  The limit is the value, in the current
	dispersion units, corresponding 3.3% of a pixel.  Attempting to set
	the value any smaller, say with fitting of the parameter turned
	off, will still result in a returned value corresponding to the
	minumum.  If you want one of the values to be zero then the profile
	type should be set to Gaussian or Lorentzian.  If you want a fixed
	value smaller than the minimum the only workaround is to resample
	the spectrum to finer pixels.

STATUS:	A smaller minimum could be put into the code but there will always
	be some point and so no changed is currently planned.
