Notes. The first column specifies the type of sample (mocks or real data). The second and third columns give, respectively, the name of the sample and the number of objects it contains. Where available, in the following columns, we also provide the number of stars, galaxies, and quasars separately. Note that the numbers provided here include a magnitude cut of 17.0 < r ≤ 24.3 (see text for details).
