Properties of R1/2, rd. X-labels from 1 to 34 mark the rank number of the 33 optical TDEs in Yao et al. (2023) and AT2024tvd in Yao et al. (2025). The solid red circle plus error bars marks the results for AT2020wey. The solid red five-point star plus error bars marks the modified results in AT2020wey. The solid circle in dark green (rank number 35) shows the results for the first flare in AT2019avd, and the upward arrow in purple (rank number 36) shows the R1/2, rd ∼ 11 that is higher than the current marked position for the second flare in AT2019avd. The open circle (rank number 37), solid triangle (rank number 38), and open triangle (rank number 39) plus error bars in dark green show the results for PS1-10adi, SDSS J0946+3512, and J2334+1457. The open circles plus error bars in red show the remeasured R1/2, rd of the 32 TDEs (except AT2020wey) in Yao et al. (2023). The horizontal solid and dashed line in blue and red mark the mean value and ± standard deviation of the R1/2, rd in Yao et al. (2023) and the remeasured R1/2, rd through ZFPS r-band background-subtracted light curves reported here.
