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 |
|
SHY 776. Bayesian analysis by Shaya & Olling (2011) indicates very |
Shy2011 |
|
high (near 100%) probability pair is physical. |
