FeII FWMH fitting

[Bovornpratch]

Hi,

I am performing some fitting to the MgII emission line area and I have a 2 questions about the FeII emission lines.

1). The FeII template used is a composite template correct? I see a mixture of references in the FeII text files
2). How can I set the limit of the FeII_FWHM_UV to a different value other than [1200,18000]? I can see in the code the line

fit_params.add('Fe_uv_FWHM', value=pp0[1], min=1200, max=18000)

which can be modified but I would prefer a less hacky solution.

Thanks!

the FeII template is not a composite one but is connected with different templates (just used the most confident segment in different templates)

   If you want to change the limits, you need to edit the source code. This choice (1200,18000) is the most flexible one for large sample AGN fitting. For some particular objects with very large or small Fe FWHM, you can change them.
