Note
The epoch is T0. Sarma notes that the probable error of a single velocity (1.2
km/s) is large for spectrograms of this type of star obtained with the Mills
spectrograph, and he suggests some additional cause of velocity variation may
be acting. Lucy & Sweeney adopt a circular orbit. The star is the brighter
member of A.D.S. 16672: B is 7.5m at 13.0" and shares the proper motion of A.
