Notes. The weighted means and mean uncertainties (Δχ2 = 1) are given for the BAO-peak parameters (α⊥, α∥) and for the Lyα- bias parameters. The best-fit χ2 is listed along with d.o.f. equal to the number of bins minus the number of parameters. The final column gives N6.18 defined as the number of mock sets with 
. The mean of N6.18 would be 4.5 if the errors on (α⊥, α∥) were Gaussian. In the cross-correlation fits, we fix bQSO = 3.34 and f = 0.95916, and in the combined fit, f = 0.95916.
