Differences between the high-mass and low-mass CDFs for the first 4 neighbors. The BASS measurements (black data points) are compared to two toy models: model 1 (blue), which assumes standard M_BH − M_* and M_* − M_halo relations, and model 2 (orange), which additionally includes a M_BH − M_halo correlation at fixed M_*. Different line styles correspond to different assumptions for the M_BH − M_* relation.
