T90 = 4.3 sec. Hardness ratio (energy fluence ratio) = 1.88951361249
S(15-50 keV) = 6.505754e-07 S(50-150 keV) = 1.6938742e-06
The dash-dotted line and the dashed line traces the fluences calculated from the Band function with Epeak = 15 and 150 keV, respectively. Both lines assume a canonical values of alpha = -1 and beta = -2.5.
