  1. Column (1) presents the flare name, Column (2) presents the observation duration, Column (3) presents the observed flux during each epoch in the units of Ph cm−2 sec−1, Column (4) presents the spectral index α at Eb when fitted with logparabola model, here Eb is the scale parameter, Column (5) presents the curvature parameter β when fitted with logparabola model, Column (6) presents the test statistics (TS) of the detection.
