SDSS A_V measurements #41

Closed changhoonhahn closed 4 years ago

changhoonhahn commented 4 years ago

We need A_V measurements for SDSS in order to:

sample A_V directly for SFR = 0 population
implement non-slab model that uses the A_V distribution

TStarkenburg commented 4 years ago

SDSS_Av SDSS galaxies. Classification is from Brinchmann+2004. TauV is from their continuum fit (best fit from three metallicity BC01 models), so does not depend on the spectra. A_V = TauV * 1.086

changhoonhahn commented 4 years ago

Based on these SDSS distributions, I've settled on sampling A_V from a truncated normal distribution for now (see notebook and 7fd01fe6461a90294ac9b4c68549dac14b43db57).

Closing this issue for now.
