Modelling the Milky Way โ I. Method and first results fitting the thick disc and halo with DES-Y3 data
ABSTRACT We present a technique to fit the stellar components of the Galaxy by comparing Hess Diagrams (HDs) generated from trilegal models to real data. We apply this technique, which we call mwfitting, to photometric data from the first 3 yr of the Dark Energy Survey (DES). After removing regions โฆ
