Appendix A: Additional figures
In this appendix, we present figures that show the dependence of measured eclipse depth on the choice of aperture radii and on the choice of different reference star combinations. We also display the correlations between raw light-curve flux and detrending parameters.

Fig. A.1
Dependence of rms, measured eclipse depth, and red noise factor on aperture size and reference ensemble for the K band. The left panel shows the dependence on aperture size. The top subpanel displays the rms of light-curve O–C residuals. The middle subpanel displays corresponding eclipse depths. The bottom subpanel displays the time-averaging red noise factor (i.e. β2 as denoted in Sect. 3). The results derived from three cases of baseline functions (BF) are shown for comparison: the chosen best BF, a candidate BF that results in similar BIC to the best BF, and a linear BF that produces a poor fit. The vertical dotted line refers to the chosen aperture size, while the dash-shaded area refers to the 1σ confidence level of our reported result. The right panel shows the dependence of rms, measured eclipse depth, and red noise factor on different reference star ensembles. These ensembles have been sorted according to rms for display purposes, with the best one being #1. The subpanels on the right are organized in the same manner as for the left. |

Fig. A.3
Correlation between instrumental parameters (i.e. variables in the baseline function) and the normalized flux for the K band. The first row shows the flux before baseline correction, while the second row shows the flux after baseline correction as a comparison. In these plots, x and y refer to the relative positions, and FWHMx and FHWMy refer to the full-width at half maximum of the marginalized PSF, both in pixels. |
