The Intrinsic Production Rate Part III
Here is a new update on the intrinsic production rate calculation for the galaxies (continuation from Part I and Part II).
Spectra Parameters
Dust: I played around with these a bit, and verified setting dust_type=0; dust_index=0 is equivalent to keeping dust_type=2 and setting dust2=0.
Really, to fix things I had to turn the nebular emission model off
add_neb_emission=0
What seems to be happening is that the ionizing photons were being absorbed by gas around stars.
Updated Plots
Here is what the spectra looks like now:
And here are the xi_ion values
These look much better.
There looks like there is some discretization in the second plot (similar to what Mark Dickinson found when looking at emission lines). I think this is probably due to some sort of discretization in how FSPS is creating the spectra, or where the spectral lines are, but I should dig into this more, to make sure it isn’t an unwanted discreteness in the redshift values of the galaxies.
