The time-averaged spectrum from \nT0-0.256 s to T0+69.377 s is best fit by a Band function with \nEpeak = 175 +/- 12 keV, alpha = -1.29 +/- 0.02, and \nbeta = -1.98 +/- 0.02 (chi squared 578 for 477 d.o.f.).\n\nThe event fluence (8-1000 keV) in this time interval is \n(3.5 +/- 0.1)E-05 erg/cm^2. The 1.024-sec peak photon flux measured \nstarting from T0+1.024 s in the 8-1000 keV band \nis 17.9 +/- 1.4 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary; \nfinal results will be published in the GBM GRB Catalog.\"",
