The time-averaged\nspectrum from T0-0.512 s to T0+51.712 s is well fit by a Band function\nwith Epeak = 256.2 +/- 11.8 keV, alpha = -1.07 +/- 0.02, and\nbeta = -2.38 +/- 0.09.\n\nThe event fluence (10-1000 keV) in this time interval is\n(6.24 +/- 0.07)E-05 erg/cm^2. The 1.024-sec peak photon flux measured\nstarting from T0+4.480 s in the 10-1000 keV band is 66.8 +/- 1.0 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
