In preparation for the Second LAT Gamma-Ray Burst (GRB) catalog, we explore the use of the LAT low-energy (LLE) data selection to detect bursts with gamma-ray energy below 100 MeV.
Here we present the sample of GRBs that are detected at these energies through a Bayesian Block analysis of all Fermi Gamma-ray Burst Monitor (GBM) triggers collected in 8 years of Fermi mission.
In particular, we compare the temporal characteristics of this sample of GRBs with those of the brightest bursts detected above 1 MeV by the GBM.
Finally, we examine the properties of a subset of events which are not detected above 100 MeV (LLE-only GRBs).
