Caption: Figure 2.

Polarization vector maps of M82, rotated 90° to represent the inferred magnetic field direction. Upper left: 53 μm fractional polarization. Upper right: 154 μm fractional polarization. Bottom left: position angle only overlaying intensity contours. The first contour starts at 2 × 10⁴ MJy sr⁻¹ with increments of 2 × 10⁴ MJy sr⁻¹. Bottom right: position angle only overlaying intensity contours. The first contour starts at 4 × 10³ MJy sr⁻¹ with increments of 4 × 10³ MJy sr⁻¹.
