Notes.

(a)

Epoch of maximum velocity (circular orbit).

(b)

HD 98839 = 56 UMa.

(c)

HD 218634 = 57 Peg.

(d)

A solution with P = 10481 d and e = 0.36 is also possible. However, considering the unusual mass function of 0.128 ± 0.007 M⊙, this solution is less likely than the shorter solution which has a more common mass function of 0.030 ± 0.001 M⊙.
