The ligo.skymap package provides tools for reading, writing, generating, and visualizing gravitational-wave probability maps from LIGO and Virgo. It provides several tools that used to live in LALSuite and elsewhere, but in the form of a tiny Python package that is easier to install. Some of the key features of this package are:

• Script bayestar-localize-coincs: BAYESTAR, providing rapid, coherent, Bayesian, 3D position reconstruction for compact binary coalescence events

• Script ligo-skymap-from-samples: Create 3D sky maps from posterior sample chains using kernel density estimation

• Script ligo-skymap-plot: An everyday tool for plotting HEALPix maps

• Module ligo.skymap.plot: Astronomical mapmaking tools for perfectionists and figure connoisseurs

See the installation instructions or the full documentation.

Note: Since the migration of these tools from LALSuite is very recent, the modules, scripts, and documentation in this package are subject to change.
