GRB 201215A: BALROG localization (Fermi Trigger 629706213 / GRB 201215266)
J. Burgess, F. Kunzweiler, B. Biltzinger, F. Berlato, & J. Greiner (all MPE Garching) report:
The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger
629706213 at 06:23:28 on 15 Dec. 2020 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) = 192.9+/-3.8 deg
Decl.(2000.0) = 18.1+/-3.8 deg
We estimate an additional systematic error of 2 deg.
