Updated emission lines and continuum models #572

Closed HiramHerrera closed 1 year ago

The following Pull Request updates:

BossDr9_fiducial_continuum model dispersions based on the results found by Rodrigo in slide 6 of this presentation to reproduce eBOSS DR16 QSO dispersion found by PCA method.
Emission line model, in order to better reproduce the results of PICCA Mean Flux on EDR data.

LyA Region	LyB region

This new model also addresses the correlation between CIV Equivalent Width and Magnitude as found on observational data. Previous mocks didn't have such correlation

Happy to merge once Alma is happy, she know more than I do about this part of the code.

I wouldn't worry too much about the "mean continuum" plot above, since the data has redshift errors that are not present in the mocks (are they?), and as we saw in Youles et al. (2022) this has an effect in the mean continuum measured by Picca.

I think you can merge @HiramHerrera
