ligo.skymap

The ligo.skymap package provides tools for reading, writing, generating, and visualizing gravitational-wave probability maps from LIGO and Virgo. Some of the key features of this package are:

GW170817 localization

This illustration of the position of GW170817, prepared using ligo.skymap, illustrates the main features of this package: rapid localization of compact binaries with BAYESTAR 1, three-dimensional density estimation 2 3, cross-matching with galaxy catalogs, and visualization of gravitational-wave sky maps. Reproduced from 4.
