Comparison between BTL and on-disk LAT flares.

Notes. Rise time, difference between GBM 32–76 keV and > 100 MeV peak times (ΔPeak), peak flux value of the gamma-ray emission, and the position of the active region for the five BTL flares detected with the LAT and with sufficient statistics to perform a time-resolved analysis (top table) and the impulsive on-disk flare of September 6, 2011 (bottom table). The criteria for the selection of the on-disk flare is described in the text. The BTL flare that is not considered here is the flare of January 6, 2014, due to a lack of sufficient coverage by the LAT. We do not list the value of ΔPeak for SOL2021-07-17 because the GBM did not detect any significant emission from this event.
