North-south asymmetry in coronal rotation at different altitudes (1.1, 1.4, and 2.5 solar radii). For each altitude, the solid and dotted lines are contours of rotation rate at 360 nHz and 440 nHz respectively. The colour indicates the difference in rotation rate between north and south at the same latitude, therefore values are anti-symmetric about the equator.
