GRB 211102B: BALROG localization (Fermi Trigger 657554740 / GRB 211102587)
B. Biltzinger, F. Kunzweiler, F. Berlato, J. Burgess & J. Greiner (all MPE Garching) report:
The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger
657554740 at 14:05:35 on 02 Nov. 2021 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) = 315.4+/-3.0 deg
Decl.(2000.0) = 1.5+/-1.5 deg
We estimate an additional systematic error of 2 deg.
