NICER background-subtracted light curves of eRO-QPE1 spanning 3 yr, derived by fitting the source with a blackbody spectral model (tbabs×zbbody) in each 200 s GTI. Red points denote source detections, while black points indicate GTIs in which a blackbody component was not required at >1σ. There are 92 flares, which we fit with the exponential model described in Section 2.2 (gray lines).
