discov_num notes refcode
RBR 21 51 Peg = Helvetios.
2001.7340: PA is measured in zenith mode. If data collected in
equatorial mode, PA = 244.9. Confirmation of the pair should establish
the correct theta value. Rbr2011d
Based on van Leeuwen (2007) parallax, the candidate companion VlF2007
would have a separation of 45 au. Due to its relatively high proper
motion, as additional observation will be able to determine whether
the star shares common proper motion or is a background star. Rbr2011d
CHARA Array Limb-darkened diameter 0.748 +/- 0.027 mas, CIA2008c
R = 1.266 +/- 0.046 \rsun.
CHARA Array Limb-darkened diameter of A : CIA2013c
R = 1.1501 +/- 0.0195 \rsun, L = 1.2962 +/-0.0156 \lsun,
