IceCube 201021A: Swift follow-up of Fermi J1725.5+1312
Abstract
We have analysed 2.7 ks of XRT data for Fermi J1725.51312 (Buson et al. GCN Circ. 28751). The data were taken in Photon Counting (PC) mode. XRT observations establish a refined position for the source: R.A. 17:23:14.09, Dec. +14:20:59.1, with a 90% containment radius r_90 = 2.9". The best-fit power-law spectrum has a photon index alpha = 1.5 (+0.8, -0.4) and observed flux f_X = 6.5 (+3.1, -2.5) x 10-13 erg cm-2 s-1 (0.3-10 keV) The observed flux is lower by a factor of 4 to 10 by comparison to its XMM slew observation on 2006-09-04 (XMMSL2 J172313.9+142100, OsID:9123400002) We do not claim this source as a counterpart to IceCube 201021A from these observations.
