Results on background-subtracted ZFPS light curves of AT2020wey in rest frame. Top: ZFPS gr-band background-subtracted light curves (symbols in blue and in red) in flux space, including the data points with measurements smaller than 3 times of their uncertainties. Horizontal dashed red line marks flux equal to zero. Middle and bottom: Best fitting results to the background-subtracted light curves with measurements larger than 3 times of their uncertainties around the TDE related flare with MJD-58000 between 1100 and 1200, with symbols and line styles having the same meanings as those in the middle panel and right panel in Fig. 2.
