Notes. The auto-correlation fit uses the combination Lyα(Lyα) × Lyα(Lyα) + Lyα(Lyα) × Lyα(Lyβ) described in de Sainte Agathe et al. (2019). The fits are over the range 10 < r < 180 h−1 Mpc. Errors on BAO parameters correspond to CL = 68.27%, while the other parameters have errors corresponding to Δχ2 = 1. The parameter βq is fixed for the cross-correlation fit. The bottom section of the table gives the minimum χ2, the number of data bins (Nbin) and free parameters (Nparam) in the fit, the probability, the effective redshift, the correlation coefficient (ρ) for the BAO parameters, and the χ2 for the fit with the fixed fiducial BAO peak position.
