Planck 2020 (NPIPE) data

This page provides a web interface to some of the NPIPE products hosted at NERSC.
For full access, interested parties are encouraged to apply for a user account.

The codes are available on github: github.com/planck-npipe

Maps

The full data release is available on the NERSC global file system at /global/cfs/cdirs/cmb/data/planck2020.
frequency maps in the format they will appear on the Planck Legacy Archive

Likelihoods

Likelihood codes are distributed as a module for the COBAYA sampler:

Lollipop (low-l polarized EE-BB-EB): github
Hillipop (high-l temperature and polarisation): github

Data are downloaded automatically or can be downloaded here.

MCMC chains

We provide results from MCMC exploration chains, as well as yaml files used for Cobaya runs and covariance matrices here.
