Subject
GRB 090406: pseudo-z= 0.91 from prompt emission spectrum
Date

A. Pelangeon & J-L. Atteia (LATT-OMP) report:

We used the spectral parameters of GRB 090406
provided by Golenetskii et al. (GCNC 9103)
to compute the spectral pseudo-redshift(**) of this burst
detected by Konus-Wind and Konus-RF instrument.


We find a pseudo-redshift pz= 0.91 +/- 0.10
