ligo.skymap

###########

The `ligo.skymap` package provides tools for reading, writing, generating, and

visualizing gravitational-wave probability maps from LIGO, Virgo, and KAGRA.

Some of the key features of this package are:

*  `Command line tool bayestar-localize-coincs`_ and

   `bayestar-localize-lvalert`_: BAYESTAR, providing rapid, coherent, Bayesian,

   3D position reconstruction for compact binary coalescence events

*  `Command line tool ligo-skymap-from-samples`_: Create 3D sky maps from

   posterior sample chains using kernel density estimation

*  `Command line tool ligo-skymap-plot`_: An everyday tool for plotting

   HEALPix maps

*  `Module ligo.skymap.plot`_: Astronomical mapmaking tools for

   perfectionists and figure connoisseurs

To get started, see the `installation instructions`_ or the `full

documentation`_.

   :alt: 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 [#BAYESTAR]_, three-dimensional density estimation

   [#GoingTheDistance]_ [#GoingTheDistanceSupplement]_, cross-matching with

   galaxy catalogs, and visualization of gravitational-wave sky maps.
