Table 1: 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 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 Extrasolar Planets Encyclopaedia (cf. footnote 1) or the cited papers. Where none of this was available the distance is estimated from Hipparcos parallaxes.
