Le Floch (IRFU/CEA)\n\nOn behalf of the Mass AssociatioN for GRavitational waves ObserVations\nEfficiency (MANGROVE) Team.\n\nWe spatially cross-matched the LIGO/Virgo S200213t event skymap\n(90% probability volume) with the MANGROVE [1] galaxy catalog\nand found 33991 compatible galaxies. We classified as \"compatible\"       \nwith the skymap, a galaxy which fulfills the two following conditions:\n\n-Its 2D position in the sky has to be in the 90% of the 2D skymap\nprobability distribution.\n-Its distance has to fall within the 3 sigma distance error\nlocalization at the position of the galaxy.\n\nWe rank galaxies according to the grade Gtot presented in\nDucoin et al. [1] which uses the galaxies stellar mass in addition to\ntheir localisation to assess their probability of hosting the event.\nThe stellar mass is estimated from the WISE1 luminosity. \nThe list of the 20 first galaxies ranked by this grade is given below,\nthe full list of galaxies is available at

identified\nas AGN from mid-infrared color criterion [1], 0 otherwise.\n\nThe estimated mass completeness of the catalog for the skymap\ndistance is about 56%.\nThis calculation was made by comparing the total mass within\nthe Mangrove catalog to the stellar mass function derived from\nthe GAMA survey [4] in the range 224 +/- 90Mpc (within 1 sigma\nof the skymap [1]).\n\nThe MANGROVE catalog compiles information from the GLADE\ncatalog [2] and AllWISE catalog [3] up to 400Mpc and is\nfully available on the MANGROVE website\n(https://mangrove.lal.in2p3.fr). This website\nalso provides tools to download a complete list of\ncompatible galaxies for every gravitational wave event\nbelow 400Mpc of the LVC O3 run with the possibility to add\nobservational constraints.\n\n[1] Ducoin et al., ui.adsabs.harvard.edu/abs/2020MNRAS.492.4768D/abstract\n[2] D��lya et al., ui.adsabs.harvard.edu/abs/2018MNRAS.479.2374D\n[3] Cutri et al., ui.adsabs.harvard.edu/abs/2014yCat.2328....0C\n[4] Wright et al., 2017, MNRAS, 470, 283",
