Distance-to-centre distribution of Coma Ber’s leading and trailing tail members. The orange lines depict the kernel density estimate of samples from the radial distance while the black dots and grey bars depict radial bins mean and standard deviation of 100 bootstrap realisations from the tail’s members. A Gamma distribution was fitted to these bootstrap realisation and its median value (black solid lines) and one-sigma (blue dashed lines), two-sigma (orange dashed lines) and three-sigma (green dashed lines) confidence intervals are also plotted. The vertical arrows indicate the radial bin with densities exceeding the two-sigma (orange arrows) and three-sigma (green arrows) levels.
