XFaster Documentation
XFaster is a power spectrum and parameter likelihood estimator for cosmic microwave background (CMB) data sets. It’s a hybrid of two types of estimators: pseudo-\(C_\ell\) Monte Carlo estimators, like MASTER/PolSpice, and iterative quadratic estimators. The full description of the pipeline, including the math and assumptions used, are in the pipeline paper. These docs focus on the code implementation.
The basics of running the code are given in Quick Start. More details of the math can be found in Algorithm, and a detailed review of the code is given in Tutorial.
