GRB 260312B: BALROG localization (Fermi Trigger 795001611 / GRB 260312407)
T. Preis (University of Innsbruck) & J. Greiner (MPE Garching) report:
The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger
795001611 at 09:46:46 on 12 March 2026 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) = 26.3 deg
Decl.(2000.0) = -8.3 deg
The 1 sigma statistical error radius is 2.2 deg.
We estimate an additional systematic error of 1 deg.
