A sample rotational sequence is shown for each of our two primary runs in late March and late April. Each sequence starts with the upper left image and moves clockwise; the rotational phases are given in the lower right corner of each frame. In each case, the jet approximately toward the east (left) in the first time step (labeled J1) completes a simple, nearly face-on spiral through the sequence, while the other jet (J2) exhibits significantly larger projection effects, presumably due to having a source region closer to the rotation pole, resulting in a narrower cone being traced out and, during both time frames, cutting along our line of sight with one side of the swept-out cone.
