Advanced LIGO and Virgo should secure the first direct detections of gravitational waves. Compact binary mergers, promising gravitational-wave sources and possible progenitors of short gamma-ray bursts, are predicted to have rapidly fading optical counterparts. Optical follow-ups will demand timely and accurate parameter estimation. In the last LIGO—Virgo science run, a triangulation code produced sky maps for pointing telescopes. The improved Bayesian sky map algorithm described here will complement the exhaustive but higher latency Markov-chain Monte Carlo parameter estimation.
