1-s peak spectrum unavailable, because battblocks failed to determine burst durations.
T90 = N/A sec. Hardness ratio (energy fluence ratio) = N/A
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.
