Note: Significance levels of the K-S test for the null hypothesis that
observations and the simulations are alike and are drawn from the same parent
population (HG82 and UZC-SSRS2 columns). Significance level of the K-S test for
the null hypothesis that the HG82 and the UZC-SSRS2 group catalogue are alike and
are drawn from the same parent population (HG82 vs. UZC-SSRS2 column).
