RST1706 Hipparcos parallax 19.27 +/- 1.23 mas. Dynamical parallax 19.6 mas,
masses 0.90 and 0.71 Msun. RST 1706 is an example of a neglected
binary, discovered by R.A. Rossiter in 1934 but observed so rarely Rst1955
that only now, after a nearly full revolution, the first orbit could
be proposed. Tok2012b
