Two instances of A, which is subject to shot noise, for the 2.5 h variable planet and a THEM with T_h = 600 K, at 3 pc, and 90 degrees inclination. The instance shown with a gray line correctly identifies the input moon orbital period (26.4 h), in contrast to the instance represented by a red line. The red area shows the stable moon orbit region, between the host’s Roche limit and the Hill sphere.
