Differential photometry of ZTF and ATLAS performed at the centroids of the host galaxies of the initial 70 TDE candidates. Data points with < 3σ significance are shown as hollow circles, > 3σ as solid circles, and > 5σ are further highlighted with black edges. Spectroscopic observation epochs are marked with vertical dashed green lines. Epochs of X-ray peak are marked with vertical solid gray lines. For TDE candidates with detected optical flares, we show Gaussian process model fits following the procedures described in Sect. 4.3.1.
