TITLE:   GCN CIRCULAR
NUMBER:  6244
SUBJECT: GRB 070402: pseudo-z~3.36 from spectral parameters of the prompt

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

We have used the spectral parameters of GRB 070402
provided by Golenetskii et al. (GCNC 6243) to compute
the spectral pseudo-redshift** of this burst detected by
the IPN network (Hurley et al., GCNC 6241, GCNC 6242).

We find a pseudo-redshift pz= 3.36 +/- 1.00
