Caption: Figure 3.

Line integral contour (Cabral & Leedom 1993) maps of the polarization data. Notice the transition of the position angle from vertical to planar to the southwest in the 53 μm map and to both the northeast and southeast in the 154 μm map. A cut in polarization S/N (debiased) of 2σ was used to form these images, which allows the general trend in position angle to be traced further into the halo and along the disk.
