Query: A Comparison of Radio Axis with Host Galaxy Plane Axis in Seyfert
  Galaxies   We use the radio axis as an indicator of the orientation of the obscuring
torus in Seyfert galaxies, and analyze the difference between the position
angles of extended radio structures and host galaxy major axis of Seyfert 1 and
Seyfert 2 galaxies. We find that Seyfert 1's are less likely to have extended
radio structures along the host galaxy major axis, while Seyfert 2's have these
structures distributed in most directions. We also find a zone of avoidance in
the distribution of position angles; both Seyfert 1's and Seyfert 2's seem to
avoid close alignment between the radio axis and the host galaxy plane axis.
These results are analyzed from the point of view of a model in which Seyfert
1's have their obscuring torus axis aligned preferentially along the host
galaxy disk axis, and Seyfert 2's have their torus axis laying at an
intermediate angle between the galaxy disk and its axis.
