The Echo-Location: aka the BAT Targeted Search Portal

This web application hosts and manages live, autonomous, analyses of BAT data in the form of targeted searches around times provided by other instruments, with the goal of (echo)locating an associated gamma-ray transient.
All information on this site is preliminary and is provided to the broader community on a best effort basis to aid time-critical decision making.
The analyses hosted on this site rely on the GUANO autonomous spacecraft commanding pipeline (Tohuvavohu, Kennea, et al. 2020) and the NITRATES likelihood analysis (DeLaunay and Tohuvavohu, 2022). Please cite these papers if you use information hosted here.
Contact Aaron Tohuvavohu with questions or requests.

It is strongly recommended that you read the documentation before using any information provided here.
