There is no strong emission in \nthe 100-350 keV band.  T90 (15-350 keV) is (15 +- 1) sec \n(estimated error including systematics).  \n\nThe power law index of the time-averaged spectrum is 1.96 +- 0.25.  \nThe fluence in the 15-150 keV band is (2.7 +- 0.4) x 10^-7 erg/cm2.  \nThe 1-sec peak photon flux measured from T0+0.24 sec in the 15-150 keV \nband is (0.5 +- 0.1) ph/cm2/sec.  All the quoted errors are at the 90% \nconfidence level.",
