\caption[]{\label{cham_table2} Stars with proper motions from the
ROSAT sample investigated by Alcal\'a et al.\ (1995, 1997) and 
Covino et al.\ (1997). 
The classification in T Tauri stars and ZAMS and other stars is based
on the lithium criterium as applied by C97. Note however that some of the
stars classified as ZAMS stars or stars of unknown nature fall well above
the main sequence when placing them in the HR diagram with the help of
the Hipparcos parallax (Neuh\"auser \& Brandner 1998).}
