\begin{table}%T1
\caption{Presentation of our target sample and their stellar parameters.
           The objects were selected either because of an existing 
           planetary system or observational hints for a disk. See the 
           column \emph{remarks} for a classification of the targets (we 
           do not distinguish between a single planet or a planetary system). 
           Three resolved disks were also included. $V$-band fluxes are taken 
           from SIMBAD and near-IR fluxes from the 2MASS~catalogue. The
           distances are obtained either via the \emph{Extrasolar Planets 
           Encyclopaedia} (cf.\ footnote~1) or the cited papers. Where none
           of this was available the distance is estimated from Hipparcos 
           parallaxes.}\label{table:targets}
