Caption: Figure 5.

Polarization vector map of NGC 253 at 89 μm, with vectors rotated 90° to represent the inferred magnetic field direction. Left: vectors with length proportional to the fractional polarization. Right: position angle only, overlaying intensity contours. The first contour starts at 2.8 × 10⁴ MJy sr⁻¹ with increments of 2.8 × 10⁴ MJy sr⁻¹. The dashed line indicates the long axis of the tilted disk (position angle = 51°, Pence 1980).
