Table 4 is organized as follows: Col. 1, source name; Col. 2, other name; Col. 3, redshift; redshifts marked with ``*'' are taken from the following pubblications: 0223+34 Willott et al. (1998); 0316+16 Labiano et al. (2007); 1225+36 Lawrence et al. (1994); 1600+33 photometric redshift from Stanghellini et al. (2005); 1607+26 Stanghellini et al. (1993); Col. 4, optical identification. The source 3C 455 has been re-classified as galaxy by Hes et al. (1966); Cols. 5 to 8, depolarisation indices DP; Col. 9, rotation measure RM derived from our new Effelsberg observations; Col. 10, ls-1: the least square fit of the linear regression of the values in Col. 9; Col. 11, rotation measure RM derived from our new Effelsberg observations, complemented with data from Tabara & Inoue (1980); Col. 12, ls-2: the least square fit of the linear regression of the RM values in Col. 11; Col. 13, rest frame RM calculated using the RM $_{\rm obs+TI}$ values.
