Left, middle, and right panels: distributions of z, β and M_UV for the entire sample at 2.9 <z< 6.6, respectively. In each panel, the blue and red histograms correspond to the distributions for udf-10 and mosaic, respectively. A two-sample Kolmogorov-Smirnov test (K-S test) results in the p-value of 0.84, 0.25, and 0.32 for the two z, β and M_UV distributions, respectively, indicating that the distributions of the values in the two fields cannot be distinguished from each other.
