The detection of electromagnetic (EM) counter- parts will help immensely in characterizing its GW source, probing the nature of counterparts associated with compact binary coalescences, and enriching our understanding of their environments. The localized error regions (or patches) in the sky obtained from observations by GW detectors will be a few tens to a few hundreds of square-degrees wide, and may not be observable in a single night using an EM telescope. We have developed an algorithm to tile the patch, optimize the observing sequence, and maximize the probability of finding the EM counterpart. We have accounted for practical observing constraints, including the diurnal circle, target visibility and telescope availability. We performed extensive simulations to compare our algorithm with existing follow-up algorithms and found that the former does better in maximizing the probability of finding EM counterparts. |
