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
