A probabilistic code written in python to jointly fit spectrophotometric data

requiem2d

requiem2d is a python code created to fit HST/WFC3/G141 grism spectra along with all available HST, Spitzer and ALMA photometric measurements. It is capable of fitting spatially resolved stellar populations while including global and semi-resolved information within a fully Bayesian framework. The Bayesian model is discussed in our paper.

requiem2d relies on Grizli to analyze grism data. It also uses pymc3 to sample the posteriors. FSPS and python-FSPS are used for generating stellar population synthesis models. These are core dependencies of requiem2d, and they should be installed properly before requiem2d.
