Boxplots of the response variable and of the activity indicators A, γ, and FWHM_SN for each segment of the optimal partition found by the bp method when applied to the α Cen B RV time series. We recall that a boxplot is a graphical tool that visualizes a distribution; the median is shown by the thick horizontal line, while the box extension defines the interquartile range (IQR), being bounded by the first (Q₁) and third (Q₃) quartiles. The upper and lower limits of the vertical dashed lines (the whiskers) are defined as min {max(X), Q₃ + 1.5 · IQR} and max {min (X), Q₁ − 1.5 · IQR}, respectively, where X indicates the sample to be represented. Outliers beyond the whiskers (if any) are represented as empty dots.
