discov_num notes refcode
WRH 33 Aa,Ab: 31 Cyg = omi 1 Cyg. A spectroscopic, eclipsing, astrometric,
interferometric binary. A is the zeta Aurigae-type binary V695 Cyg.
It is spectrum K4Ib+B3-4.
Aa,Ab: Star D noted as single. See Wilson (1950) for extensive notes
on comparison of measures with orbits, mass estimates, etc. WRH1950a
Aa,Ab: Reality of these measures would seem more questionable than
those published in 1950. WRH1951
Aa,Ab: Attempted to observe visually this 10yr binary which passed
eclipse late in 1951. WRH1954b
Aa,Ab: Correction for magnitude difference should increase this
estimated separation. WRH1955
Aa,Ab seen single in 1953, resolved once again by McAlister in 1980. McA1983
1983.4905: Our ACFs do not resolve the system with much confidence
(theta ~168 deg, rho ~0".029). Bag1984a
