Welcome to the Gravitational Wave Treasure Map

The Treasure Map is designed to help coordinate electromagnetic followup of gravitational-wave (GW) events. It allows observers to easily report their planned and executed observations in search of counterparts to GW events, and to query the reports of other observers, in a programatic way. The goal is to enable coordination between observatories in order to minimize unnecessary overlap in these searches and find the counterpart as quickly and as efficiently as possible.

Please register for an account, so that you can programatically query the Treasure Map.

For more details on how to use the Treasure Map see our User Guide.

The Treasure Map is being designed and developed by:
Samuel Wyatt, University of Arizona
Aaron Tohuvavohu, University of Toronto
Iair Arcavi, Tel Aviv University
Dave Sand, University of Arizona
D. Andrew Howell, Las Cumbres Observatory
Michael Lundquist, University of Arizona
Curtis McCully, Las Cumbres Observatory
Austin Riba, Las Cumbres Observatory

Please direct any general inqueries to Iair Arcavi.

If you use the Treasure Map in your research, please cite GCN Circ. 26244 in addition to the circulars and/or papers of the teams whose pointing information you use.

Coverage Calculator


Calculate the coverage of the GW localization over time, with choices to limit the coverage calculation to particular sets of instruments, wavelengths, or depth. All fields are optional, but cuts on depths must have an associated unit. If an empty form is submitted, the total reported coverage regardless of depth or band is computed. Once a HEALPIX pixel has been first covered, it is marked as done, to avoid double counting probability when the same field is covered multiple times. After clicking, be patient, it may take up to 20 seconds to fully compute the coverage profile.
