\begin{table}%t2
\caption{\label{Tab:detection}Detection rate (expressed in~\%) as a function of orbital period
and parallax. The percentage is given along with its binomial error; the total number of stars
in the bin is listed between parentheses. For $\varpi > 5$~mas and $100 \le P(\rm d) \le 3000$, the detection rate comes
close to~100\% when removing
SB2~systems, systems with composite spectra or with a poor-quality spectroscopic orbit.}
