Fig. 2

Distributions of radial-velocity program stars by values of trigonometric parallax a); its relative error b); and proper motion c). In panel a), the top axis shows distances in pc; the two nearest (d< 3 pc) MCC stars are outside the plotting area. To enable a direct comparison of the two different samples in panel c), a separate histogram (hatched) is shown for a subset of MCC stars within 25 pc.
