GRB 210801A: BALROG localization (Fermi Trigger 649519043 / GRB 210801581)
Abstract
The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger 649519043 at 13:57:18 on 01 Aug. 2021 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) = 238.2+/-1.5 deg Decl.(2000.0) = -40.8+/-0.9 deg We estimate an additional systematic error of 2 deg.
