MCA 63 Aa,Ab: lam Cyg = 54 Cyg. A is a spectroscopic binary, which has now
been resolved by interferometry into a close and rapidly moving pair.
1986.567: The separation of this partially resolved pair was
calculated under the assumption of zero or otherwise known magnitude
difference. Tok1985
STT 413 Only elements P and T have been amended by Starikova (1982) from the Sta1982b
orbit of Baize (1983). Baz1983a
