TITLE: GCN CIRCULAR NUMBER: 16439 SUBJECT: GRB 140622A: Swift-XRT refined Analysis DATE: 14/06/22 21:51:03 GMT FROM: Phil Evans at U of Leicester D.N. Burrows (PSU), J.A. Kennea (PSU), P.A. Evans (U. Leicester), B.P. Gompertz (U. Leicester), J.P. Osborne (U. Leicester), M. de Pasquale (INAF-IASFPA), A. Maselli (INAF-IASFPA), V. Mangano (PSU) and V. D'Elia report on behalf of the Swift-XRT team: We have analysed 7.3 ks of XRT data for GRB 140622A (D'Elia et al. GCN Circ. 16433), from 103 s to 30.9 ks after the BAT trigger. The data are entirely in Photon Counting (PC) mode. The enhanced XRT position for this burst was given by Osborne et al. (GCN Circ. 16434). The light curve can be modelled with a power-law decay with a decay index of alpha=7.1 (+/-0.9). If the light curve continues to decay with a power-law decay index of 7.1, the count rate at T+24 hours will be 5.3 x 10^-21 count s^-1 The results of the XRT-team automatic analysis are available at http://www.swift.ac.uk/xrt_products/00602278. This circular is an official product of the Swift-XRT team.
