Just to followup, if I use the nebular templates (no special line marginalisation template) then the emission lines are seen as expected (because nebemlineinspec==True
). However, for strong AGN like sources here it is better to fit lines independently of the cloudy grids as Ben's paper suggests.
It makes sense because thenebemlineinspec
is turned off when fitting lines outside of the available grids, but then the best-fit
should incoporate the gaussian fits right?
I am wondering the same thing as @themiyan , was this ever answered?
Hi, it looks to me like the marginalization is not happening for some reason, or is not properly fitting the emission line amplitudes even when nebemlineinspec
is False. I suggest setting use_eline_prior
to False to avoid using the cloudy grid predictions at all. Also make sure you are using the most recent release of prospector (1.3.0)
What is the best way to reproduce the
best-fit
spectrum whennebular_marginalization
template is turned on?As in the fig below, the stored best-fit does not have any fitted lines, even when a higher resolution model is regenerated using
out_model.mean_model
and removing alllsf
effects.I don't think the fitted lines are being accurate here, the
eline_sigma
comes out ~ 100km/s which is incorrect for the above spectrum, but even the high-R reconstruction doesn't show any reconstructed lines there.
