Comparison of the Stokes V light curve to an auroral ring model. The top plot shows the Stokes V light curve including all radio data, phase folded to the rotation period of AU Mic of 4.86 days. The data points represent the flux density averaged over the entire bandwidth in 1-h time bins. The two shaded regions show the two periods of burst visibility, where the red region shows when positive bursts can be produced and the blue region shows the same for negative bursts. The bottom plot shows a model of the visibility of the auroral rings, where P_* represents the visibility of the auroral ring, akin to the probability of detecting a burst, multiplied by the predicted sign of emission.
