    Distribution

    T90 vs. Hardness ratio plot

    T90                                   = N/A sec.
    Hardness ratio (energy fluence ratio) = N/A
    

    S(15-50 keV) vs. S(50-150 keV) plot

    S(15-50 keV)  = N/A
    S(50-150 keV) = N/A
    

    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.
