The power law index is -1.22 +/- 0.03 and\nthe cutoff energy, parameterized as Epeak, is 449 +/- 55 keV\n\nThe event fluence (10-1000 keV) in this time interval is\n(1.43 +/- 0.04)E-5 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+11.65 s in the 10-1000 keV band\nis 11.4897 +/- 0.2869 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
