| Title | Efficient power spectrum estimation |
| Description | NaMaster is a C library, Python module and standalone program to compute full-sky angular cross-power spectra of masked fields with arbitrary spin and an arbitrary number of known contaminants using a pseudo-Cl (aka MASTER) approach. The code also implements E/B-mode purification and is available in both full-sky and flat-sky modes. |
| Type Of Material | Improvements to research infrastructure |
| Year Produced | 2019 |
| Provided To Others? | Yes |
| Impact | The software is used by the wider community (both large collaborations and individual groups) for a broad range of analyses in cosmology, and has been implemented in the pipelines of the international experiments I am a member of. |
