Phase-folded TESS light curve of the HD 165052 binary system as observed during sectors 91 and 92 (grey symbols), and shifted in phase by −0.08 (black symbols). The mean error per phase-binned data point is 1.6 10⁻⁴ mag. The red continuous line illustrates the synthetic curve computed with the set of parameters taken from Rosu et al. (2023). The magenta long-dashed curve shows the best-fit synthetic curve with the inclination left as a free parameter, whilst the blue short-dashed curve corresponds to the best-fit for an inclination of i = 22.7°. The model parameters are given in Table G.1.
