Stack of the 100 mocks cross-correlation for two different ranges of r_⊥ with the points representing the reconstructed correlation function and the lines representing the fit correlation function (over the range 10 <r< 160 h^-1 Mpc). Blue and red represent the Lyα+Continuum type and Lyα+Continuum+Metals types, respectively. The four black dashed lines indicate the positions of the four peaks of the metal-quasar correlations. The trough at r_∥ ≈ −60 h^-1 Mpc is due to the SiII(119.3)- and SiII(119.0)-quasar cross-correlations, at r_∥ ≈ −21 h^-1 Mpc to the SiIII(120.7)-quasar cross-correlation, and at r_∥ ≈ + 103 h^-1 Mpc to the SiIII(126.0)-quasar cross-correlation.
