Left: Total radio intensity contours on top of a color scale map of the RMs after applying RM synthesis. The scales are in rad m⁻². The contour levels are (3, 5, 8, 16, 32, and 50) × 15.5 μJy beam⁻¹ at a resolution of 32″ × 26″. The foreground RM of our Galaxy has not been subtracted. Right: Same total intensity contours as in the left panel on top of the RM error map. The beam size is shown at the bottom left corner of each image. A cut-off of 5 × rms noise is applied to all these maps. Regions close to the minor axis of the disk are excluded due to unrealistic RM values.
