Top panel: phase-folded light curve, after correcting for long-term trends, binned in 5 minute intervals (black points), along with the best-fit full phase curve model from our joint analysis (red line). Middle panel: same as top panel but with an expanded vertical axis to detail the fitted phase curve modulation and secondary eclipse signal. The contributions to the phase curve from ellipsoidal (B₂), atmospheric brightness (B₁), and beaming (A₁) modulations are plotted individually with black solid, dot-dashed, and dotted lines. Bottom panel: plot of the corresponding residuals from the best-fit model.
