Faraday-rotation angles of S-, X-, and Ka-band signals simulated for the Juno PJ-63 occultation at ingress (left) and egress (right). The vertical axis displays the absolute value of the rotation angle on a logarithmic scale; the dip approximately five minutes before closest approach in the ingress panel corresponds to the sign reversal of the rotation as the ray geometry crosses the perpendicular field configuration. The surface corresponds to the 1 bar level.
