GRB 230308A: BALROG localization (Fermi Trigger 699975152 / GRB 230308564)
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
699975152 at 13:32:27 on 08 March 2023 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) = 104.5+/-7.6 deg
Decl.(2000.0) = 67.3+/-1.3 deg
We estimate an additional systematic error of 2 deg.
