ligo.skymap: Advanced Python Tools for Probability Sky Maps

The ligo.skymap Python package includes a number of advanced tools for working with GW probability sky maps.

  • Publication-quality astronomical mapmaking built on Astropy (ligo.skymap.plot.allsky)

    A figure made with ligo.skymap.plot.allsky

  • Functions for manipulating distance posteriors (ligo.skymap.distance)

  • Probabilistic airmass plots (ligo-skymap-plot-airmass)

    A probabilistic airmass plot.

  • The rapid sky localization code BAYESTAR, which is used to produce the initial sky maps for CBC events but can also be used to create simulated sky localizations.

  • The postprocessing tool that creates updated sky maps from MCMC samples (ligo-skymap-from-samples)
