A fast power spectrum and likelihood estimator for CMB datasets
Implementation by A. Gambrel, A. Rahlin, C. Contaldi.
XFaster is a fast power spectrum and likelihood estimator for CMB datasets. It has most recently been used for the SPIDER B-mode polarization results, but is intended to be generically useful for modern CMB observatories.
