discov_num notes refcode
BNU 6 Aa,Ab: del Aql = 30 Aql. A is a spectroscopic binary, now resolved by
speckle interferometry.
Hipparcos astrometric solution adopts some elements from the HIP1997d
spectroscopic orbit of Kamper et al. (1989). Kpr1989
The spectroscopic binary remains unresolved, BNU 6 is not real Msn2023a
and the speckle measure from Bonneau & Foy 1980 is no good. Bnu1980b
