Simulated A_ell distributions for BH-LCs (black), detached MS-MS binaries (orange), and contact binaries (cyan). Contours outline the regions of constant density. The simulation of BH-LCs is described in Section 6.2, while the other simulated populations are described in Paper I. BH-LCs typically have a somewhat larger mean amplitude than detached MS-MS, by between 0.25 to 0.5 dex depending on the period, but the amplitudes of contact binaries can be even larger.
