The TESS light curves of V505 Lac for Sectors 16, 56, and 57. The measurements are represented by gray dots. The TESS light curves for the representative epochs, 14650, 17980, and 18032, are represented by black dots and correspond to Sectors 16, 56, and 57, respectively. The solid lines indicate the synthetic light curves calculated using the WD binary star modeling code. The residuals from the synthetic light curves of each sector are illustrated below the curves.
