The files below contain the catalogue and the results of its cross-match with GW sky maps used in the analysis presented in Veronesi et al. 2024b (https://arxiv.org/abs/2407.21568).Short description of the content: Quaia_z15.csv: catalogue containing all the objects of Quaia with a redshift estimate of z<=1.5. The parent catalogue is presented in Storey-Fisher 2024 (https://ui.adsabs.harvard.edu/abs/2024ApJ...964...69S/abstract) and the related data is publicly available at https://zenodo.org/records/10403370; completeness.csv: completeness for the 8 linear redshift bins between z=0.0 and z=1.5. Different columns correspond to different cuts in bolometric luminosity. The values of the different luminosity thresholds can be found in the parent paper; result_crossmatch.csv: results of the cross-match between the AGN catalogue and 159 GW sky maps. For each skymap we indicate the ID of the GW event, the value of average completeness within the 90 per cent credibility level localisation volume, the sum of the probability densities associated to each AGN within such volume, weighted by the number density of the catalogue, and the difference of the logarithm of the single-event likelihood calculated at f_AGN=1 and the one at f_AGN=0.
