Light curve residuals from the W-D model fit to the TESS data. The lower panel is a zoomed-in view of the residuals shown in the inset box in the upper panel. The red solid line represents the synthetic curve computed from the 11 frequency fit to the out-of-eclipse data. The residuals from the frequency fit are offset from zero by +20 mmag for clarity and are plotted as the blue symbols. The vertical solid and dotted lines indicate the primary and secondary minimum epochs, respectively.
