Notes. (a) The units for the parameters are given in Tables B.2– B.6. (b) The superscript of ‘inf/sup’ indicates inferior vs. superior conjunctions. (By default we give inferior conjunctions. Superior conjunctions are indicated by asteriks.) (c) More explicitly, this is the angle between the orbital planes of the inner binary and the outer triple orbit.
