Distribution of the time constants across derivations. Boxplots of the time constants (τ
, increase; τ
, decrease) across derivations in the average map (AV; Figure 1A) and in individual maps (Figure 2). In addition, time constants estimated for derivation C3 against average reference and C3A2  are plotted to the right of each boxplot (left and right oriented triangle, respectively). Boxes represent the lower quartile, median, and upper quartile. The notch indicates the 95% confidence interval of the median. Maximum whisker length is 1.5 times of the inter-quartile range. They extend to the most extreme data value that is not an outlier. Outliers are indicated by +.
