\tablefoot{Linear and circular polarizations were measured in
the $V$ filter except a series of linear polarization data from the
literature measured in white light and noted~[w]; 
\tablefoottext{(\star)}{1215$-$002 is classified as a BL~Lac by Collinge~et~al. (\cite{COL05});
Sbarufatti et~al. (\cite{SBA05}) re-determined the redshift of
1256$-$229 ($z = 0.481$) and considered this object as a BL Lac.
