Volume-averaged cross-correlation function χ as a function of transverse separation in three radial bins (black data points). The orange line depicts the median posterior model of the quasar-galaxy two-point correlation function. Assuming a power law form, ξ_QG = (r/r₀^QG)^−2.0, we constrain the quasar-galaxy cross-correlating length r₀^QG. The uncertainties reflect the confidence interval for a Poisson distribution for the number of clustering galaxies per bin that corresponds to 1σ in Gaussian statistics (Gehrels 1986).
