Notes.

^(a)

The units for the parameters are given in Tables 6–9.

^(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.
