A. Pelangeon & J-L. Atteia (LATT-OMP) report:
We have used the spectral parameters obtained for the most intense part
of GRB 070724B -- from T0+24.8 to T0+41.2 s, Konus time
(V. Pal'shin, Ioffe Inst., private communication) --
observed by Konus-Wind (Golenetskii et al., GCNC 6671)
to compute the spectral pseudo-redshift(**) of the first burst
localized by SuperAGILE (Feroci et al., GCNC 6668).
We obtain: pz= 1.10 +/- 0.20
We thank V. Pal'shin for having kindly performed the spectrum analysis
and providing us the spectral parameters.
