Singer (NASA-GSFC)�report on behalf of the GROWTH collaboration:\n\nBased on the new LALInference map (GCN 26505), we re-ran our galaxy cross-match from GCN 26479 with the HAWC position (GCN 26472)and the GLADE v2.3 catalog (Dalya et al., 2018), to identify sources within the 90% LIGO/Virgo credible volume and within a 3-sigma radius of the HAWC candidate. Our updated search yields only three matching galaxies, which were in our previously reported list of galaxies (GCN 26479). All of the galaxies in our previous list are within the 95% 3D credible level in the LALInference map; we report only those galaxies still within the 90% 3D credible level.\n\nThe distance parameters from the LALInference localization at the\nposition of the HAWC candidate are DISTMU= 272.35 Mpc and DISTSIGMA= 44.52 Mpc.\n\nIn the table below, we give the right ascensions and declinations in\ndegrees and luminosity distances in Mpc. The \"GW C.L.\" column\nprovides the LIGO/Virgo 3D credible level within which the galaxy is\nfound (smaller values mean more consistent with the GW position). The\n\"HAWC sigma\" column gives the separation from the HAWC position,\ndivided by the HAWC 1-sigma error radius.\n\n| RAJ2000 � �| DEJ2000 � | Dist �| GW C.L. | HAWC sigma |\n| ---------- | --------- | ----- |-------- | ---------- |\n| 322.821228 | +5.553754 | 338.7 | 81 � � �| 2.59 � � � |\n| 322.749084 | +5.108610 | 330.8 | 78 � � �| 2.62 � � � |\n| 323.034882 | +4.482058 | 340.7 | 86 � � �| 2.99 � � � |\n\nGROWTH is a worldwide collaboration comprising of Caltech, USA; IPAC,\nUSA; WIS, Israel; OKC, Sweden; JSI/UMD, USA; U Washington, USA; DESY,\nGermany; MOST, Taiwan; UW Milwaukee, USA; LANL USA; Tokyo Tech,\nJapan; IITB, India; IIA, India; LJMU, UK; TTU, USA; SDSU, USA and\nUSyd, Australia.
