+==== Tracking Offsets ====
+The offsets tab in the sidebar allows setting an offset from a track in any of the three standard coordinate frames used by bigdish.
+Additionally, a fourth option is provided to offset by an angle defined in the frame of the target (parallel/perpendicular to track). This is defined as a right handed frame ordered as (pointing direction, travel direction, cross direction). Crucially, unlike the other frames, This frame gives a true angle of arc which is defined only by the commanded offsets independent of source position.
