GRB 231018A: BALROG localization (Fermi Trigger / GRB 231018521)
T. Preis, B. Biltzinger, J. Burgess & J. Greiner (all MPE Garching) report:
The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger
at 12:30:10 on 18 Oct. 2023 were automatically fitted for spectrum
and sky location with BALROG (Burgess et al. 2018, MNRAS 476, 1427;
Berlato et al. 2019, ApJ 873, 60).
The best-fit position (1 sigma statistical errors) is:
RA(2000.0) = 1.2+/-0.5 deg
Decl.(2000.0) = 51.5+/-0.2 deg
We estimate an additional systematic error of 1 deg.
