T90 = 21.984 sec. Hardness ratio (energy fluence ratio) = 1.64622758354
S(15-50 keV) = 7.274393e-07 S(50-150 keV) = 1.5112587e-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.
