Same as Table 2 but for QSOs.

Notes. The χ²/d.o.f. is obtained by computing the monopole of the two-point correlation functions of the Uchuu QSO mocks for the best-fit model parameters and comparing to the observed monopole of the DESI One-Percent sample two-point correlation function, in the separation range ∼5 h⁻¹ Mpc to ∼30 h⁻¹ Mpc. This was the same method used to obtain the best-fit V_mean (in km s⁻¹), and f_sat parameters used to generate our UCHUU One-Percent mock lightcones.
