Left panels: Data (dots) and model (solid lines) light curves of UU Aqr. Top to bottom: Steady‐light component, the curve of the long‐term changes, the ensemble flickering curve, and the single flickering curve. Vertical dotted lines mark the ingress/egress and mideclipse phases of the WD. A dashed curve depicts the error bars in each case. A dotted curve in the ensemble panel shows the average contribution of the Poisson noise to the scatter at each phase. Vertical ticks mark the ingress/egress phases of the two asymmetric structures seen in the eclipse maps. Middle panels: Corresponding eclipse maps in a logarithmic gray scale. A cross marks the center of the disk and a dotted line shows the primary Roche lobe. A solid contour line is overplotted on each eclipse map to indicate the 3 σ confidence level region. Right panels: Asymmetric component of the eclipse maps in a logarithmic gray scale. Additional dotted lines show the ballistic stream trajectory, a reference circle of radius ﹩0.6R_{\mathrm{L}\,1}﹩, and semicircles of radii ﹩0.2R_{\mathrm{L}\,1}﹩ and ﹩0.32R_{\mathrm{L}\,1}﹩. Labels in the ensemble panel depict the location of the asymmetric sources 1 and 2. The secondary is to the right in each panel, and the stars rotate counterclockwise. Scale bars on the right side depict the log(intensity) scale in each case.
