TITLE: GCN CIRCULAR NUMBER: 13638 SUBJECT: GRB 120805A: Enhanced Swift-XRT position DATE: 12/08/14 08:26:46 GMT FROM: Phil Evans at U of Leicester P.A. Evans (U. Leicester) reports on behalf of the Swift-XRT team: We have reinvestigated the XRT position of GRB 120805A. Using 2.6 ks of XRT Photon Counting mode data and 2 UVOT images, we find an astrometrically corrected X-ray position (using the XRT-UVOT alignment and matching UVOT field sources to the USNO-B1 catalogue): RA, Dec = 216.53836, 5.82525 which is equivalent to: RA (J2000): 14 26 09.21 Dec (J2000): +05 49 30.9 with an uncertainty of 2.7 arcsec (radius, 90% confidence). This position is 10" from the unenhanced XRT position reported in GCN Circ. 13592. The size of the astrometric correction, which is responsible for this shift, was such that the enhanced position was initially rejected and not circulated automatically. Position enhancement is described by Goad et al. (2007, A&A, 476, 1401) and Evans et al. (2009, MNRAS, 397, 1177). This corrected position is our best XRT position, and is 1.5 arcsec from the optical counterpart proposed in GCN Circ. 13591, supporting the identification of that source as the afterglow. We thank Daniele Malesani for drawing this to our attention. This circular is an official product of the Swift-XRT team.
