Comparison of the dynamical and astrometric mass sums of the objects included in Table 4. Using the Discoverer designation, we have highlighted those objects that exhibit a very large difference between their dynamical and astrometric masses. The solid line is not a fit; it only shows the expected one-to-one relationship. In both axes, the quantity shown is the second quartile from Table 4. BU146's astrometric mass falls out of scale to the right, so we depict it with an arrow at the level of its dynamical mass (see Section 4 for further details). This is the same situation with FIN370 adopting the Gaia parallax, however, if we adopt the Hipparcos parallax our orbit will lead to a much smaller mass, indicated by the green diamond (for further details see Section 4).
