Our choice of fitting functions also reproduces the following features of
the polarization distribution:
- 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
40% with longitudinal apparent field at the edge
(Fig. 12).
- 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).
- 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).
- 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).
- 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).
