TITLE: GCN CIRCULAR NUMBER: 12363 SUBJECT: GRB 110918A: pseudo-z= from prompt emission spectrum DATE: 11/09/20 13:31:38 GMT FROM: Jean-Luc Atteia at Lab d Astrophys.,OMP,Toulouse J-L. Atteia (IRAP-UPS/CNRS)& A. Pelangeon report: We used the spectral parameters of GRB 110918A provided by Golenetskii et al. (GCNC 12362) to compute the spectral pseudo-redshift(**) of this burst localized by IPN (Pal'shin et al., GCNC 12358). We find a pseudo-redshift pz= 0.28 +/- .07 ** cf.http://cosmos.ast.obs-mip.fr/projet/v2/calculation_pz.html -- Jean-Luc Atteia atteia@ast.obs-mip.fr IRAP Observatoire Midi-Pyrenees Phone 0 561 332 884 14 Avenue E.
