Notes. 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]; $^{((\star))}$ 1215-002 is classified as a BL Lac by Collinge et al. (2005); Sbarufatti et al. (2005) re-determined the redshift of 1256-229 (z = 0.481) and considered this object as a BL Lac.
