Location is at\nRA: 33.84 (+4.77/-6.39 deg  90% PSF containment) J2000\nDec: 31.61 (+2.75/-2.28 deg 90% PSF containment) J2000\n(GCN circular 27941).\n\nWe performed two types of analyses for the follow-up. The first is for\na steady source in archival data and the second is a search for a\ntransient source. We assume a power-law spectrum with an index of -2.3\nfor both analyses.\n\nSearch for a steady source in archival data:\nThe archival data spans from November 2014 to May 2018. We searched\ninside the reported IceCube error region.\nThe most significant location, with p-value 3.02e-4 (8.27e-2 post-trials),\nis at RA 35.51 deg, Dec 33.55 deg (��0.16 deg 68% containment) J2000.\nWe set a time-integrated 95% CL  upper limit on gamma rays at the\nmaximum position of:\n\nE^2 dN/dE = 3.85e-13 (E/TeV)^-0.3 TeV.cm^-2.s^-1\n\nSearch for a transient source.\n\nSince the IceCube event fall inside the HAWC field of view,\nwe report on the result for the transit of the IceCube\nposition.\n\nData acquisition started on 2020/06/13 18:10:07 UTC and ended\n2020/06/14 18:32:13 UTC.\nThe most significant location, with p-value 1.35e-3  (3.20e-1 post-trials),\nis at RA 38.63 deg, Dec -30.55 deg (��0.09 deg 68% containment) J2000.\nWe set a time-integrated 95% CL upper limit at the position of\nmaximum significance of:\n\nE^2 dN/dE = 1.46e-11 (E/TeV)^-0.3 TeV.cm^-2.s^-1\n\nHAWC is a very-high-energy gamma-ray observatory operating in Central\nMexico at latitude 19 deg. north. Operating day and night with over\n95% duty cycle, HAWC has an instantaneous field of view of 2 sr and\nsurveys 2/3 of the sky every day. It is sensitive to gamma rays from\n300 GeV to 100 TeV.",
