RSS 35 This previously uncataloged double star was a Hipparcos double entry
system. The first measure is determined from the individual positions
listed by Rousseau et al. Rss1996
Optical pair, based on study of relative motion of the components
using the method of apparent motion parameters. Kiy2008
