TITLE: GCN CIRCULAR NUMBER: 17264 SUBJECT: GRB 150101A: Swift-XRT refined Analysis DATE: 15/01/01 18:53:05 GMT FROM: Phil Evans at U of Leicester B. Sbarufatti (INAF-OAB/PSU), V. Mangano (PSU), M.C. Stroh (PSU), D.N. Burrows (PSU), C. Pagani (U. Leicester), A.P. Beardmore (U. Leicester), P.A. Evans (U. Leicester), P. D'Avanzo (INAF-OAB), V. D'Elia (ASDC) and A. Vargas report on behalf of the Swift-XRT team: We have analysed 8.5 ks of XRT data for GRB 150101A (Vargas et al. GCN Circ. 17261), from 68 s to 18.8 ks after the BAT trigger. The data are entirely in Photon Counting (PC) mode. The enhanced XRT position for this burst was given by Goad et al. (GCN Circ. 17262). The source is fading with alpha >0.6. If the light curve continues to decay with a power-law decay index of , the count rate at T+24 hours will be 7.9 x 10^-5 count s^-1 The results of the XRT-team automatic analysis are available at http://www.swift.ac.uk/xrt_products/00623158. This circular is an official product of the Swift-XRT team.
