TITLE: GCN GRB OBSERVATION REPORT NUMBER: 5499 SUBJECT: GRB 060901: pseudo-z from spectral parameters of the prompt DATE: 06/09/03 14:57:54 GMT FROM: Jean-Luc Atteia at Lab d Astrophys.,OMP,Toulouse A. Pelangeon & J-L. Atteia (LATT-OMP) report: We have used the spectral parameters of GRB 060901 provided by Golenetskii et al. (GCNC 5498) to compute the spectral pseudo-redshift** of this burst detected by INTEGRAL (Mereghetti et al., GCNC 5491). We find a pseudo-redshift pz= 2.0 +/- 0.5 ** cf. http://www.ast.obs-mip.fr/grb/pz
