Cumulative cost of pairs of variables (C_cum; shown as bullets), computed for the normalized preflare time profiles during the 24 hours leading to the flares of sample S​_SEA (flare ID is shown along of the x-axis and associated to specific flare events in the last column of Table A.1). The size of the plot symbols (bullets) relate to the inverse of C_cum, i.e., larger symbols indicate a larger similarity of two time profiles. Respective mean values, ⟨C_cum⟩, computed across all flares of a certain type are given to the right of the figure. Red and blue color indicate eruptive and confined flares, respectively.
