Example of detection rates vs. mass for α Cen A for different definitions: blind test with a fap threshold of 1 % (brown, all ΔT_spot, see Sect. 4), SN_peak > 6 (solid black line, ΔT_spot1, see Appendix D.1), SN_glob > 6 (dahed black line, ΔT_spot1), and theoretical false positive of 1% (in red, ΔT_spot1, see Appendix D.2). The dashed red line indicates the uncertainty on the red solid curve. The vertical green line is the detection limit obtained in Theia Collaboration (2017).
