TITLE: GCN CIRCULAR NUMBER: 15318 SUBJECT: GRB 131004A: Correction to XRT refined analysis DATE: 13/10/07 07:09:57 GMT FROM: Phil Evans at U of Leicester P.A. Evans (U. Leicester) reports on behalf of the Swift-XRT team, There was a mistake in the "Swift-XRT refined analysis" circular (GCN Circ. 15311) in which it was erroneously stated that the light curve was consistent with a constant source. In fact, the light curve is decaying as a power-law with an index of 1.01 (+/- 0.07). We apologise for any confusion caused. As ever, the full light curve and related GRB products are online at http://www.swift.ac.uk/xrt_products/00573190 This circular is an official product of the Swift-XRT team.
