GRB 240329A: BALROG localization (Fermi Trigger 733441392 / GRB 240329905)
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
733441392 at 21:43:07 on 29 March 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) = 248.9 deg
Decl.(2000.0) = -1.4 deg
The 1 sigma statistical error radius is 3.4 deg.
We estimate an additional systematic error of 1 deg.
