Fermi-GBM and Swift-BAT Data Release Related to Analysis of Gravitational-Wave Candidates from the Third Gravitational-wave Observing Run

This material contains the data products associated with A Joint Fermi-GBM and Swift-BAT Analysis of Gravitational-Wave Candidates from the Third Gravitational-wave Observing Run [1]. It is based, in part, on data products associated with GWTC-2.1 [2][3] and GWTC-3 [4][5] from the LIGO Scientific Collaboration, the Virgo Collaboration, and the KAGRA Collaboration provided under a Creative Commons Attributional 4.0 International license. For more information, see the paper (https://arxiv.org/abs/2308.13666) and the included README.txt.

The data release includes the following directories:

• 3sigma_upper_limit_maps: 3 sigma flux upper limits reported by GBM as a function of sky position over a 10-1000 keV energy range.
• 5sigma_upper_limit_maps: 5 sigma flux upper limits reported by GBM and BAT as a function of sky position over a 15-350 keV energy range.
• gbm_targeted_results: GRB candidates from the GBM Targeted Search.
• gbm_temporal_offset_analysis: input files to the time offset analysis applied to GBM on-board triggers and candidates from the GBM Untargeted Search.
• bbh_model_fluxes: predicted gamma-ray fluxes over the 10-1000 keV energy range for likely BBH mergers.
• gw_localizations: GW localization files used to overlay the 90% credible area onto GBM upper limits as a function of sky position.
• m1_m2_contours: 90% credible region paths for the GW component masses m1, m2.

The data release also includes a set of example scripts to show how the contents of the data files are used. Refer to the included README.txt for more details.
