The measured component separation, $\\rho=42 \\pm 2$ mas, is consistent with the one derived from the known spectroscopic orbit and distance. In particular, our result implies a total mass of the binary of $M_{\\rm t}=M_{\\rm g}+M_{\\rm wd}=3.7^{+3.5}_{-1.7} \\rm M_{\\sun}$, which is in good agreement with the value $M_{\\rm t}=2.7^{+1.2}_{-0.6} \\rm M_{\\sun}$ derived from the spectroscopic orbit solution for the red giant and evolutionary contraints.
