Notes.

(a)

Average of proper motions given in PPMXL and UCAC4.

(b)

The listed radial velocity is the weighted average of all measurements.

(c)

The listed distance is from the BANYAN kinematic analysis (Malo et al. 2013). At 65 pc, the projected sky separation of the two stars is ~1700 AU.

(d)

We assume V-band magnitude uncertainties of ~0.3 mag.
