GRB 240527B: BALROG localization (Fermi Trigger 738511436 / GRB 240527586)
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
738511436 at 14:03:51 on 27 May 2024 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) = 128.0 deg
Decl.(2000.0) = -15.2 deg
The 1 sigma statistical error radius is 3.4 deg.
We estimate an additional systematic error of 2 deg.
