4.1.5 Fitted polarization features

Our choice of fitting functions also reproduces the following features of the polarization distribution:

  1. There is a V-shaped region at the onset of the flaring of the main jet in which the polarization is close to zero on-axis and rises to values $\approx$40% with longitudinal apparent field at the edge (Fig. 12).

  2. Between 4 and 8arcsec from the nucleus in the flaring region, the main jet polarization drops to a very low level over the entire width (Fig. 12).

  3. In contrast, the corresponding region of the counter-jet shows a transverse apparent field with monotonically increasing polarization on-axis with a much lower degree of polarization towards the edge (Fig. 16).

  4. In the outer region, the degree of polarization increases monotonically with distance from the nucleus in both jets, with a transverse apparent field, but the degree of polarization is always higher in the counter-jet (Fig. 15).

  5. Both jets show longitudinal apparent field at their edges, with a degree of polarization approaching 70% at the extreme outer edge (Figs 12 and 16).
