T90 = 7.2 sec. Hardness ratio (energy fluence ratio) = 1.8232665076
S(15-50 keV) = 2.0917968e-06 S(50-150 keV) = 4.891682e-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.
