* I didn't use 'gauss' option before in moment object. I am using 'moment' option, maybe you could try it to see if it works.
* The second problem is caused by some typoes. It will be fixed soon.
To get the right wavelenght, it could be used like this (in your case):
{{{
IDL> wavel=obj->getlam(iwin)
IDL> n_wavel=n_elements(wavel) ;get the number of wavel
IDL> wavel=wavel[0:n_wavel-2] ;cut the last element of the 'wavel'
}}}
Hope this helpful.

Problem nr 1) "and I cannot find a way to extract from objm the values for the different lines that had been fitted. Any idea to do it? or I should cut the window in sub-windows? or there are any other way to do it (maybe without objects..)? Also, is there any way to see the values of wavelength in the xcfit window?"
Answer: We have not yet written software to deal with multiple lines in a given window, I suggest you extract the relevant window from the object and work directly with xcfit/cfit to fit the lines you need.
Problem nr 2) "Why am I getting one value more than the number of pixels?"
Answer: Yes, this is a bug, the last element should not be included. I have now fixed the method.

Of course you can use 'traditional' methods and once you have your wavelength and intensity simply use a routine like gauss_fit...
