Notes. For each reference of BW measurement in the literature, we indicate the derived distance d (pc), the projection factor used, the set of radial velocity data, and the source of angular diameter, which is either derived using the SBCR from (V − K) or (V − R) colors or measured by the mean of interferometric measurements. The last column indicates the color excess adopted. The last line presents the average distance and p-factor as derived from BW methods using (V − K) color. The distance measurements are summarized in Fig. 6a.
