The time-averaged spectrum from T0-0.080 s \nto T0+0.432 s is well fit by a simple power law function \nwith index -1.28 +/- 0.05 (chi squared 246 for 241 d.o.f.).\nThe event fluence (8-1000 keV) in this time interval is \n(1.07 +/- 0.03)E-06 erg/cm^2. The photon flux on the \n64 ms timescale measured starting from T0-0.016 s \nin the 8-1000 keV band is 20 +/- 1 ph/s/cm^2. \n\nThe spectral analysis results presented above are preliminary; \nfinal results will be published in the GBM GRB Catalog.\"",
