Comparison of the red (point-source assumption) HOD mock and the red2 (velocity dispersion induced FoG effect modeled) HOD mock shown with 10 (5 and 2) MHz in red (blue and green). The red results are shown as thick solid lines, and the red2 results are shown as faint solid lines. For better illustration, we artificially amplified the curves by 0.5 (1 and 2) times for 10 (5 and 2) MHz results. The FoG suppression at small scales is clearer with a smaller bin width.
