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 |
