Short answer - no.  Longer answer is a question - what do
you mean?  This is a spectral-line fitting routine and one
would be best of there were no continuum although it
does fit a spectral baseline (and slope) so I guess images
of that would be a continuum.  Currently XGAUS does not
write out those fits as images.  The example you sent previously
was a 1 Gaussian fit which is really easy so long as you only
fit the highest S/N regions.  If there is still a lot of continuum
present, then the FLUX adverb may not be adequate in that
a high continuum with no line will still look like a pixel to be
fit.  If I were you I would remove the continuum first (task
IMLIN), then run XGAUS.
