Number of flares ≥C3.0 (first panel) and number of ELP flares (second panel), percentage of flares identified as ELPs per McIntosh Class assigned to the sunspot group they appeared in (third panel), as well as difference in the distribution of McIntosh classes of sunspot regions among all flares ≥C3.0 vs. ELP flares. The difference is given in percentage points (pp). Positive values mean that the given class is more present in ELP flares. Eruptive ELP flares are shown in red, confined ones in blue. The numbers on the x-axis correspond to the numbers in parentheses given in Table D.1.
