ForeGroundBuster: Parametric component separation for Cosmic Microwave Background observations (WP6.2)

This library provides easy-to-use functions related to the maximum-likelihood formalism applied to parametric component separation. The package provides tools for

• the separation of frequency maps into component maps (Stompor et al. 2009)
• the forecast of component separation performances in terms of both characterization of the foregrounds and constraints on the post-component separation CMB angular power spectrum
  • when the model is correct (Errard et al. 2011)
  • when the sky is more complex than what assumed in the model (Stompor et al. 2016)

Tutorial

The documentation is available at https://fgbuster.github.io/fgbuster/index.html
It contains a presentation of the package, instructions about how to install and a detailed description of the API. Several examples are also worked out to showcase the main functionalities — which include component separation, forecasting the performances of a given experimental configuration. The library also includes a module that allows to both evaluate popular SEDs and define custom ones very easily.
