The cumulative distributions for both main sequence (solid curve) and subgiant stars (dashed curve) as a function of the cumulative chromospheric activity. The dotted vertical line represents the largest deviation between the distributions and hence relates to the KS test D statistic. Clearly both these populations are not drawn from the same parent distribution at a high level of significance.
