P.A. Evans (U. Leicester) reports on behalf of the Swift-XRT team:
Using promptly downlinked XRT event data for GRB 181126A, we find an
enhanced XRT position of the afterglow: RA, Dec: 152.3477, -29.6875
which is equivalent to:
RA (J2000) = 10 09 23.46
Dec (J2000) = -29 41 15.0
with an uncertainty of 2.5 arcseconds (radius, 90% confidence).
Analysis of the promptly available data is online at
http://www.swift.ac.uk/sper/873539.
Position enhancement is is described by Goad et al. (2007, A&A, 476,
1401) and Evans et al. (2009, MNRAS, 397, 1177).
This circular is an official product of the Swift-XRT team.
