discov_num notes refcode
SNA 61 Aa,Ab: The object is a 223d SB1 system. PIONIER observations reveal a
marginal detection (2.5sigma) whose best fit corresponds to dH = 4.3
+/- 1.8, rho~1.5mas. Both the large flux difference and separation are
compatible with the properties of the spectroscopic companion. Sna2014
