The following Files include: The summed GBM NaI detector lightcurve, The individual GBM NaI detector lightcurves, The BGO detector lightcurves, The GBM NaI detector lightcurves sliced by energy. The waterfall plot (all energy) showing the most significant timescale of the event, The waterfall plot with the three different spectral models (soft, normal and hard, see below). The localization of EP 240919a / GRB 240919A, with the green circle centered on the EP-WXT position with a 1 degree error radius. The healpix map for "Event 1", which is the event found by the Targeted Search and shown in these plots. The definitions for soft, normal and hard spectra are:"soft" spectrum (Band function with Epeak = 70 keV, alpha = -1.9, beta = -3.7) for a GRB."normal" spectrum (Band function with Epeak = 230 keV, alpha = -1.0, beta = -2.3) for a GRB."hard" spectrum (Comptonized function with Epeak = 1500 keV, alpha = -0.5) for a GRB.
