Top: background-subtracted and normalized light curves of 0.512 s binned Fermi-GBM TTE data and 1.0 s binned LLE data for the triggering pulse with the higher-energy photons arriving prior to the lower-energy photons. Bottom: the fitted counts spectrum (left), the model spectrum (center), and the posteriors of the model parameters (right) for the mBB function fitted to the triggering pulse.
