Distribution of orbital periods (left panel) and ΔRV_max (right panel) for model A3, including systems that did not interact. There is an anti-correlation between period and ΔRV_max, but it is possible for short period systems to have small ΔRV_max, as ΔRV_max has a strong dependence on the inclination, eccentricity, and the time lag between radial velocity observations. Larger ΔRV_max are more unambiguously correlated with short period systems.
