TDE XLF function in 0.2–6.0 keV. The blue points show the function obtained in this work, and the gray dashed line with the yellow region denotes its best fit with a power law (see Eq. (2)); the blue region with a black dashed line shows the best fit with a double power law (see Eq. (3)). The orange points show the TDE XLF for eROSITA_RU from Sazonov et al. (2021). The solid gray line shows the double power-law fit of a TDE optical luminosity function from Yao et al. (2023).
