Normalized cumulative distributions for the samples of BSSs (black solid line) compared to red and blue RGB stars (red and blue solid lines), and red and blue HB stars (red and blue dashed). In the case of Cetus (left panel), the BSSs are more concentrated than the blue HB stars and less concentrated than the red HB stars. In the case of Tucana (right panel), the BSSs are less concentrated than both the red RGB and HB samples, while they are marginally more concentrated than the blue components.
