The time-averaged spectrum\nfrom T0-1.792 s to T0+3.328 s is adequately by a simple power\nlaw function with index -1.24 +/- 0.03 (C-stat 478 for 387 d.o.f.).\n\nThe event fluence (8-1000 keV) in this time interval is\n(2.1 +/- 0.1)E-06 erg/cm^2. The 1.273-sec peak photon flux measured\nstarting from T0+0.003 s in the 8-1000 keV band\nis 2.9 +/- 0.2 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
