Cross-correlation coefficient comparison for halos with masses between 3 × 10¹² h⁻¹ M_⊙ and 1 × 10¹³ h⁻¹ M_⊙ at a 7.81 h⁻¹ Mpc voxel resolution from 30 validation samples. The dashed green line shows the mean for the cross-correlation coefficient from the mock fields, while the mean of idealised fields with only Poisson noise contributions is depicted in solid orange. The shaded coloured area shows the 1 σ region, respectively.
