Correlation function for the metal-free mocks in four ranges of μ. The black points and curves correspond to mocks with Lyα absorption but without the addition of a quasar continuum. The red points and curves correspond to mocks with the addition of a continuum. The points correspond to stacks of 100 mocks and the light curves to individual mocks. The heavy curves correspond to the input model of Table 1 (after distortion by the matrix D_AA′ (Eq. (10)) for the red curve).
