Systems with accurate interferometric masses
\label{Mdata}
Progress in long-baseline optical interferometry of close visual binaries has resulted in an increasing number of systems with accurate interferometric and spectroscopic orbits. Table \ref{tableMonly} lists the 23 systems in the literature in which the individual stellar masses have been determined to better than the limit of 3% for stars included in this review (Tables \ref{tableMR}–\ref{tableMRsup}). Again, we have examined the original material on which these masses are based and satisfied ourselves in each case – if necessary by independent orbital computations – that the error estimates we list are indeed reliable. The orbital parallaxes also yield accurate distances, which we list in Table \ref{tableMonly} as well, along with other information such as metallicity, when available.
