discov_num notes refcode
BU 1232 Only elements P, T, and a in the Starikova (1980) orbit have been Sta1980b
amended from the orbit of Muller (1978). Mlr1978a
Griffin et al. (1988) find this to be a SB but doubt its Grf1988
membership in the Hyades in spite of its inclusion by Sym1965
Wayman et al. (1965). Msn1993a
Hipparcos identified the pair as a candidate for Hyades membership. HIP1998
However, this is a Hyades non-member Grf1988
