Schwartz, C. Wigger, W. Hajdas, A. Zehnder, and K. Hurley, report:
The preliminary fit to the time-integrated RHESSI spectrum of
GRB060805B (Hurley et al., GCN 5407; Butler, GCN 5414) between 30 keV
and 10 MeV is a Band function with
alpha = -0.66 +0.12/-0.10
beta = -2.52 +0.16/-0.22
E0 = 240. +45/-40. keV
Epeak = 320. +/-20. keV
The 30 keV-10 MeV fluence is 1.13 +/- 0.046 E-4 erg/cm^2.
