GRB 191004B: Correction to KonusWind GCN 25974
Abstract
The redshift of GRB 191004B mentioned in GCN 25974 was incorrect, the correct one is z = 3.503 (D'Elia et al., GCN circ. 25956). Thus, assuming the redshift z=3.503 and a standard cosmology model with H_0 = 67.3 km/s/Mpc, Omega_M = 0.315, and Omega_Lambda = 0.685 (Planck Collaboration, 2014), we estimate the following restframe parameters: the isotropic energy release E_iso is 1.08(0.10,+0.12)x10^53 erg, the peak luminosity L_iso is 3.01(0.86,+0.87)x10^53 erg/s, and the restframe peak energy of the timeintegrated spectrum, Ep,i, is 775(95,+122) keV. With these energetics, the burst lies within the 68% prediction bands for both 'Amati' and 'Yonetoku' relations built for the sample of 138 long KW GRBs with known redshifts (Tsvetkova et al., ApJ 850 161, 2017). I apologize for possible inconvenience.
