M_BH obtained from the SE method from Rakshit et al. (2020) plotted vs. the corresponding values from Wu & Shen (2022). The open squares are the unshifted values and the red short-dashed line indicates the best linear fit. The blue diamonds represent the Rakshit et al. (2020) shifted by a factor 2.5; in this case the blue long-dashed line, which represents the best linear fit, nearly overlaps the one-to-one correlation illustrated by the continuous black line.
