discov_num notes refcode
SNA 7 The object is marginally resolved with rho~0.5mas, although with large
relative uncertainty. Given the distance of 947pc (Sota et al. 2014,
ApJS 211, 10) this pair probably corresponds to the known SB2
(P=33.1d, a1+a2 sin i = 0.6au; Thackeray et al. 1966, MNRAS 134, 97). Sna2014
The classification is from Thackeray (1966 MNRAS 134, 97). The star Egg1982
is part of a group associated with the cluster IC 2395 (Eggen 1982) Msn1998a
