GRB 250119B: BALROG localization (Fermi Trigger 758968026 / GRB 250119352)
T. Preis, B. Biltzinger, J. Burgess & J. Greiner (all MPE Garching) report:
The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger
758968026 at 08:27:01 on 19 Jan. 2025 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 is:
RA(2000.0) = 306.3 deg
Decl.(2000.0) = 19.3 deg
The 1 sigma statistical error radius is 1.8 deg.
We estimate an additional systematic error of 1 deg.
