STT 579 AB: 70 Vir. B is BD+14@2622.
AB: Optical pair, based on study of relative motion of the components
using the method of apparent motion parameters. Kiy2008
RBR 18 2001.0994: PA is measured in zenith mode. If data collected in
equatorial mode, PA = 241.2. Confirmation of the pair should establish
the correct theta value. Rbr2011d
CHARA Array Limb-darkened diameter 1.009 +/- 0.024 mas, CIA2008c
R = 1.968 +/- 0.047 \rsun.
70 Vir A: Combined solution, based on reduction of Hipparcos intermediate
astrometric data together with spectroscopic elements from Marcy & CPS1996a
Butler (1996). HaI2001
