The time interval of the spectral data for each \ninstrument is chosen from T0(WAM) to T0(WAM)+2 sec where \nT0(WAM) is the trigger time of WAM at 04:59:29.247 UTC.  \nThe energy ranges which we used in the joint spectral analysis \nare 14-150 keV and 100-2000 keV for Swift/BAT and Suzaku/WAM \nrespectively.  The spectral data of two instruments are fit \nwith the spectral model multiplied by the constant factor to \ntake into account the systematic uncertainties in the response \nmatrices of each instrument.  \n\nThe spectrum is well fit with a power-law with exponential cutoff \nmodel (dN/dE ~ E^{alpha} * exp(-(2+alpha)*E/Epeak)).  The constant \nfactors of each instrument agree within 10%.  No systematic residual \nfrom the best fit model is seen in the spectral data of each instrument.  \nThe best fit spectral parameters are: alpha = -0.86 +- 0.10 and \nEpeak = 1120 (-380/+780) keV (chi2/dof = 64/69).  The energy fluence \nin the 15-2000 keV band calculated by a power-law with exponential \ncutoff model for this two-second interval is 3.7 (-0.6/+1.3) x 10^-6 erg/cm2 \n(assuming the constant factor of the BAT is fixed to 1). \n\nAll the quoted errors are at the 90% confidence level.",
