T90 = 12.24 sec. Hardness ratio (energy fluence ratio) = 1.02489680701
S(15-50 keV) = 3.628004e-07 S(50-150 keV) = 3.448205e-07
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.
