The power law index is -1.22 +/- 0.04 and\nthe cutoff energy, parameterized as Epeak, is 208.00 +/- 17.10 keV\n(Castor C-stat 1074 for 483 d.o.f.).\n\nThe event fluence (8-1000 keV) in this time interval is\n(1.342 +/- 0.047)E-5 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+23.55 s in the 8-1000 keV band\nis 3.72 +/- 0.26 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
