Period-eccentricity diagram for a random sample of sources (black points) with orbits obtained by the DE-MCMC or GA algorithms from the processing the stochastic solution sample. The clear structure of period aliases is a symptom of incorrectly derived orbits and is further discussed in Holl et al. (2023). The filled green dots correspond to P and e values from ‘OrbitalAlternative’ solutions. The solid black curve indicates the maximum eccentricity attainable for an orbit that is not affected by tides, assuming a cut-off period of 5 days (see e.g., Halbwachs et al. 2005).
