Cross-correlation of the stack of the 100 mocks in four bins of μ = r_∥/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). Green and blue represent the Lyα and Lyα+Continuum types, respectively. The agreement between lines and points indicates that the distortion due to continuum fitting is well modeled by the distortion matrix D_AA′ (12). The cross-correlation is multiplied by a factor r² to show the BAO scale.
