Notes. (a) Total mass of the inner system (MA + MB from Table B.1). (b) Mass of the additional companion (or total mass of the pair in case of hierarchical systems). (c) Outer limit for orbital stability. If no information on the mass was available (marked with a question mark), a mass equal to half of that of the primary was adopted for the computation of the dynamical stability limit. (d) The circumstellar stability radius for the triple systems will not be considered for the statistical analysis, as we are not sensitive to those separations.
