Close-in look at the first subregion (the red region of Figure 3) of the large flare (highlighted in Figure 1). We attempted to fit the data as a tidal disruption event (TDE) by using a polyfit power law and comparing it to a theoretical model. The red line corresponds to the calculated polyfit, and the orange line corresponds to the theoretical shape of the data if the data were a TDE. Notably, the fit to the data points within this peak does not resemble a TDE.
