TITLE: GCN GRB OBSERVATION REPORT NUMBER: 4442 SUBJECT: GRB 060105: pseudo-z from spectral parameters of the prompt emission DATE: 06/01/06 17:02:38 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 the most intense part of GRB 060105 provided by Golenetskii et al. (GCNC 4439) to compute the spectral pseudo-redshift of this GRB, assuming that the most intense part of the burst contains half of the total fluence. We find a pseudo-redshift pz= 4.0 +/- 1.3
