GRB 210108A: BALROG localization (Fermi Trigger 631793415 / GRB 210108424)
F. Kunzweiler, B. Biltzinger, F. Berlato, J. Burgess & J. Greiner (all MPE Garching) report:
The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger
631793415 at 10:10:10 on 08 Jan. 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) = 306.9+/-4.3 deg
Decl.(2000.0) = -27.6+/-2.5 deg
We estimate an additional systematic error of 1 deg.
