GRB 241223A: BALROG localization (Fermi Trigger 756648531 / GRB 241223506)
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
756648531 at 12:08:46 on 23 Dec. 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) = 160.4 deg
Decl.(2000.0) = -34.3 deg
The 1 sigma statistical error radius is 0.8 deg.
We estimate an additional systematic error of 2 deg.
