cds-question@unistra.fractive-galactic-nucleibl-lacertae-objectspolarimetry195 polarimetric measurements of 182 BL Lac candidates from the SDSS taken with 3 different telescopes are presented. For each candidate the J2000 coordinates, its redshift, whether a source is listed in NED, the SDSS r-mag, the telescope for the observations used, the date of the observations, the exposure time for an individual exposure per position angle, the measured degree of polarization, the position angle and references to previous measurements of the sources are given. 13 objects have been observed twice. Here no entry for the coordinates is given. The redshifts, NED-listing and SDSS r-mags have been taken from Collinge et al. (2005, Cat.
