Comparison between the equatorial disk and shell models. In the panels, the black curve represents the corresponding model compared to the observed light curve. (a) The time-based light curve is projected in the radial distance on the ring plane considering the preferred mean pole orientation. (b) The normalized flux as a function as the radial distance in the sky plane, compared with the model based in the consecutive spherical shells. The residuals plus 1 for the equatorial disk (c) and shell (d) models.
