when I loaded 2048x4100 pixel images
into Ximtool from IRAF using the Display
routine they would load quickly in
seconds in Snow Leopard. Now, to load

Is there a way to get IRAF to fit

simultaneously, without adding the

some blending)? e.g., say I'd like

In fitting multiple Gaussian profiles in
splot or fitprofs, is there a way to fix
one center wavelength and let the others
vary? There appears to be only the
options of fixing all wavelengths,
shifting all wavelengths or letting all
wavelengths vary.......
