“…To determine the seven orbital parameters of this visual binary — angular semimajor axis (
), eccentricity (
), period (
), inclination (
), longitude of ascending node (
), argument of periapsis (
), and epoch of periapsis (
) — we followed the trial‐and‐error approach described by Pourbaix (1994). We employed the software tools
union and
epilogue (Pourbaix 1998b), which are described in detail with applications in Pourbaix (
1998a,b, 2000). Briefly,
union and
epilogue are used to simultaneously adjust the observations of double‐lined spectroscopic and visual binaries, as follows:
- union undertakes a global optimization of the orbital solution followed by a preliminary local search.
