check priors imposed on physical properties from tau model
changhoonhahn opened this issue · comments
NMF bases setup for SFH imposes a pretty significantly biased prior on SSFR and ZH. Lets see if a tau model does better.
I've implemented the FSPS tau and delayed tau models for provabgs.models.FSPS. Here are the priors imposed on SSFR and Z by the model:
Not as much redshift dependence as the NMF bases.
Here's how the different model priors impact derived properties
Overall, the NMF basis SFH model imposes a more restrictive prior on SSFR and Z
