Project description

CI Tests Documentation Status PyPI Conda Astropy JOSS

PySM 3

PySM generates full-sky simulations of Galactic emissions in intensity and polarization relevant to CMB experiments. It is a large refactor of PySM 2 focused on reducing memory usage, improving performance and run in parallel with MPI.

See the documentation at https://pysm3.readthedocs.io

See changes in CHANGES.rst in the repository.
