Posterior distributions for the sky location of GW190814. The contours show the 90% credible interval for a LIGO Livingston–Virgo (blue) and LIGO Hanford–LIGO Livingston–Virgo (orange) detector network based on the rapid localization algorithm BAYESTAR (Singer & Price 2016). The sky localization circulated 13.5 hr after the event, based on a LIGO Hanford–LIGO Livingston–Virgo analysis with the LALINFERENCE stochastic sampling software (Veitch et al. 2015), is shown in green. The purple contour indicates the final sky localization as presented in this paper, which constrains the source to within 18.5 deg2 at 90% probability.
