Schematics illustrating dynamical detection limits computation in ARDENT. Empty circles represent the data-driven detection limits, above which 𝒫_d ∼ 1. ARDENT models the dynamical influence of known planets in the system (diamond symbol), inducing an instability zone where additional planets are excluded. The resulting dynamical detection limits are shown in red. The inner panel illustrates the iterative mass limits update accounting for stability, with dM the difference in injected mass between two consecutive steps and δ the precision threshold (cf. Sect. 2.3.1).
