Notes. Table 5 is organised as follows: Col. 1, source name; 2, alternative name; 3, redshift; 4, optical identification; 5, polarisation percentage of the emission; 6, highest value of depolarisation; 7, highest measured rest frame RM; 8, notes: letters refer to components designetion as in references quoted in Col. 9; 9, references: 1) Cotton et al. (2003); 2) present work; 3) Cotton et al. (2003b); 4) Rossetti et al. (2009); 5) Mantovani et al. (2002); 6) Venturi & Taylor (1999); 7) Jiang et al. (1996); 8) Dallacasa et al.

am and DP values are for component C, where the peak of polarised intensity is surrounded by a region with RM in the range of $\sim$9000-10 200 rad m-2; bm and DP values are for the entire component 5; cfractional polarisations are 8.9 and 11.0% at 5 GHz for the western and eastern knots respectively (Cotton et al. 1997); polarisation is 11.3% for the dominant component with the VLA-A array at 4.885 GHz (Perley 1982); RM expected to be low but not determined with mas resolution; dpolarisation is 4.6% with the VLA-A array at 4.885 GHz (Perley 1982); epolarisation is 2.0% with the VLA-A array at 4.885 GHz (Perley 1982); fDP estimated using 8.4 GHz and the mean of four measurements between 4.6 to 5.1 GHz; gDP estimated using 8.4 GHz and the mean of four measurements between 4.6 to 5.1 GHz for component A; there appears to be different regions of high RM.
