Properties of fitted periods (upper panels) and fitted masses (lower panels) vs. true values in the blind test for a planet mass at the detection limit of Theia Collaboration (2017), for ΔT_spot1: relative residual for all peaks above the fap (left panels, false positives are in red, the dashed line on the period panel indicates the threshold between good detections and false positives we have considered), median values (middle panels, computed on all peaks above the fap, including the false positives, compared to the y = x dashed line), and 1σ uncertainties (right panels, the dashed line on the mass plot indicates a 20% uncertainty level). Open circles correspond to stars outside the B-V range of our simulations.
