Highest-f_sv strategy characteristic properties of the identified robust candidate resonances, which involve the two largest-amplitude signals, as a function of each other, with 1σ uncertainties indicated: amplitude A, frequency ω/2π, frequency de-tuning δν (see Eq. (4)), relative phase Φ (see Eq. (5)), and relative amplitude A_r (see Eq. (6)). Colours indicate the different pseudo-classes to which the stars that exhibit the candidate resonances belong. The transparent symbols indicate robust candidate resonances having 4 <  S/N <  5, whereas the full symbols indicate robust candidate resonances for which S/N ≥ 5. Grey lines indicate the zero point for the frequency de-tuning, and the faint grey horizontal lines in the last row of panels indicate the relative phases that satisfy Eq. (5).
