Notes. The linear polarization degree p is given in percent and the polarization position angle θ in degree, east of north. The data obtained in 2008 and 1999 are from Paper I and from Chae et al. (2001), respectively. For the 2011 data, V and I refer to measurements integrated over the FORS2 V and I filters, and Vc over the 0.57–0.64 μm wavelength range.
