Equatorial cut through the Hα continuum observation shown in Figure 1, averaged over latitudes −5° ≤ lat ≤  +5°. (a) Total flux F/F_peak as a function of subobserver longitude. (b) Polarized flux U/F_peak along the same strip, scaled by 10⁴ for readability. The total-flux cut shows no coherent ring-scale modulation, whereas the polarized-flux cut exhibits the structure corresponding to the ringlike pattern visible in the polarized image of Figure 1.
