GRB 230709C: BALROG localization (Fermi Trigger 710617111 / GRB 230709735)
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
710617111 at 17:38:26 on 09 July 2023 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 (1 sigma statistical errors) is:
RA(2000.0) = 267.1+/-6.5 deg
Decl.(2000.0) = -71.4+/-1.1 deg
We estimate an additional systematic error of 1 deg.
