GRB 240407A: BALROG localization (Fermi Trigger 734144396 / GRB 240407042)
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
734144396 at 00:59:51 on 07 April 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) = 347.0 deg
Decl.(2000.0) = 43.9 deg
The 1 sigma statistical error radius is 1.9 deg.
We estimate an additional systematic error of 1 deg.
