Notes.

^(a)

Measurements where the spectra show only the primary star cross-correlation peak;

^(b)

measurements with blended cross-correlation peaks which are not used to derive the orbit solution;

^(c)

measurements which are affected by the Rossiter-McLaughlin effect and are not used in the orbit solution.
