Left: Polarised intensity of IC 4662. The black contours show 5σ increasing with a factor of 1.5 plus the mean of the background (σ = 4.5 μJy/beam and mean = 42.2 μJy/beam) of the polarised emission. The orange contours show 5σ increasing with a factor of 2 (σ = 25 μJy/beam) of the total radio intensity. Right: Hα map of IC 4662 with total radio emission contours at 3σ, increasing by a factor of two (σ = 40 μJy/beam), overlaid. The magnetic field orientations are shown in green. The circular beam of 15″ is shown in the left corner.
