Correction to ATel #14199 (Swift XRT observations of the Fermi-LAT source 4FGL J0658.6+0636, positionally consistent with the IceCube high-energy neutrino alert IceCube-201114A)
Abstract
In ATel #14178 there was a mistake in the flux value we reported. We here present the corrected estimates: Analysing the Neil Gehrels Swift Observatory X-ray Telescope (XRT) data quasi-simultaneous to the IceCube-201114A arrival, we detect 4FGL J0658.6+06361 with an unabsorbed X-ray flux of 1.9 (+2.3, -0.6) x 10^-12 erg cm-2 s-1 (0.3-10 keV) and a photon index of 2.4 +/- 0.7 for an absorbed power law spectrum where the column density is left free (best fit n_H = 5.1 x 10^-21 cm^-2, wilm abundances, vern cross-sections).
