\caption{
Orbital parameters of the two planets of the planetary system \GJ\ at
epoch JD 2~449~679.6316 assuming co-planarity and $i = 90^\circ$ as
given by \citet{2004astro-ph0407441}.
The adopted stellar mass is $M_* = 0.32\; \Msol$.
$P$ denotes the orbital period,  $M$ the
mass of the planet, $a$ the semi-major axis, $e$ the eccentricity,
$\pomega$ the angle of periastron at epoch, and $q$ the mass ratio
$M/M_*$.
