Values indicate R² of linear regression of the scatter plot between two parameters, determined from ∼300 sets of conditions. NS, insignificant correlation, with a two-tailed null-hypothesis probability p > 0.02, or R² < 0.1. Bold numbers indicate strongest correlations (see Fig. 4 for scatter plots).
