Correlation matrix showing the correlation coefficients $c=\overline{c}\pm \mathrm{\Delta }c$ of all possible pairs of dimming parameters, flare parameters and CME maximum velocity v_max. The entries below the main diagonal show the mean correlation coefficient $\overline{c}$, while the entries above the main diagonal show two values: $\overline{c}-\mathrm{\Delta }c$ (lower value) and $\overline{c}+\mathrm{\Delta }c$ (upper value). The colour of the cells indicate the strength of the correlation (blue) or anticorrelation (red). The colours for the cells below the main diagonal are given by $\overline{c}$, while the colours for the cells above the diagonal are given by $\overline{c}-\mathrm{\Delta }c$.
