GRB 211008A: BALROG localization (Fermi Trigger 655401471 / GRB 211008665)
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
655401471 at 15:57:46 on 08 Oct. 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) = 296.4+/-0.5 deg
Decl.(2000.0) = 21.7+/-0.4 deg
We estimate an additional systematic error of 2 deg.
