Search for Spatial and Temporal Coincidence Between LAT/Fermi Exposure Maps and GW Sky Localizations

The poster describes a practical method to search for spatial and temporal coincidence of the LAT/Fermi coverage over a gravitational-wave sky localization. The method returns the overlap region between the two sky areas within a proper time window selected by the user. This approach offers a prompt setting of the observational strategies for searching potential electromagnetic candidates as well as a fast cross-matching between the LAT and the LIGO, Virgo and KAGRA databases for dedicated post-processing analysis.
The tasks are performed using the encoded standard method named Multi Order Coverage Map and visualized in the Aladin Desktop.
