discov_num notes refcode
MCA 44 A spectroscopic triple with the wider pair, presumably, now resolved
by speckle interferometry.
Hipparcos astrometric solution adopted some elements from the orbit of HIP1997d
Abt (1965). AbH1965
1983.3099: Elongated ACF peak suggests that the object may be double
with theta ~ 104 deg, rho ~ 0".024. HR 6237 is in fact a 1386-day SB. Bag1984a
