GRB 211021A: BALROG localization (Fermi Trigger 656506979 / GRB 211021460)
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
656506979 at 11:02:54 on 21 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) = 29.4+/-3.2 deg
Decl.(2000.0) = 27.2+/-2.1 deg
We estimate an additional systematic error of 1 deg.
