Box plots of the dynamical parameters for the SIT, from upper left to lower right: harmonic radius (R_H), velocity dispersion (σ_vr), crossing time (H₀t_c), and virial mass (M_vir). According to the dynamical parameters, the light blue shape represents the density diagram (violin plot), which shows for each dynamical parameter the form of the data distribution. The inner box on the violin plot is a representation of interquartile range of the median (red horizontal line) and its 95% of confidence intervals. We also show the mean values (blue horizontal line) and the outliers points of the distributions as black open circles, which represent the atypical points of the samples.
