$^{a}$ Coordinates in J2000 from the UKIDSS GCS DR4\@.
$^{b}$ Names in the last column are as follows: M stands for the Mayrit catalogue \citep{caballero08c}, KJN for members in \citet{kenyon05}, BNLJ for objects in Table~3 of \citet{burningham05a}, and SOri nomenclature comes from the work by \citet{bejar99}, \citet{zapatero00}, and \citet{bejar01}.
Four sources are spectroscopic binaries \citep[M258337, M459224, M873229, M1493050;][]{maxted08} and three (S36, S42, S97) are classified as non-members by \citet{sacco08}.
