Notes. The first column gives the catalogue reference number (used in Table 3) and the second column a reference name. The third column lists the number of objects with valid Tycho/Hipparcos IDs which also have | vr | ≤ 750 km s-1 and σ(vr) ≤ 10 km s-1. This is approximately the number of objects available for searching for encounters. The fourth column lists how many of these have  pc. There are duplicate stars between (and even within) the catalogues.
