Relation between integrated |AL| index (top) and average |AL| index (bottom) during the recovery phase of each storm event, and the post-storm/minimum flux ratio integrated between L = 3 and L = 6, for E = 2.1 MeV (left), E = 3.4 MeV (center) and E = 5.2 MeV (right) electron fluxes. Red, blue and black squares represent enhancement, depletion and no-change events, respectively. Vertical dashed lines separate the distribution in three groups, according to their average |AL| index
