Upper panel: stacked white light curves in the 5–7 and 7–14 μm ranges, normalized to unity and arbitrarily offset for clarity. In the combined white light curves, the sawtooth effect is largely canceled. The red lines indicate the best-fit results from our MCMC analysis, including a ramp with time and a secondary eclipse, but not the sawtooth. The phase coverage of the red line and the dashed lines denote the data points that were included in the MCMC fits. Lower panel: residuals achieved by subtracting the best-fit eclipse and ramp models from the stacked white light curves, again arbitrarily offset for clarity. The red lines indicate the zero levels for the corresponding white light residuals.
