Fig. 3.

Model fitto the total flux in a 1.2″ aperture (left panel). The diffuse stellaremission through the nuclear bulge (dotted line), AGN through torus (dashed line), ionisation cones (dashed dotted line) and the total (solid line) are shown. Model fit to the degree of polarisation (middle panel) and polarised flux (right panel) in a 1.2″ aperture are shown. Polarisation produced through the dichroic absorption by the diffuse stellar emission in the nuclear bulge (dotted line) and within the torus (dashed line), electron scattering (dashed dotted line) and total (solid line) are shown.
