• Multiband continuum<br />

imaging with HST resolves<br />

the scattering region in<br />

three cases.<br />

• In each of these, the<br />

scattering region is<br />

perpendicular to the<br />

direction of polarization, as<br />

expected.<br />

• The physical extent of the<br />

scattering region (many<br />

kpc) and the weakness of<br />

any accompanying Balmer<br />

emission rules out electron<br />

scattering: dust scattering<br />

seems to dominate.
