Major‐axis R‐band light profiles for three elliptical galaxies with directly measured SMBH masses. The best‐fitting Sérsic function is shown by the solid curve. The arrows mark the spheroids’ half‐light radii. The residuals of the data about the fit are shown in the bottom panels. (Note: Because the ﹩M_{\mathrm{bh}\,}﹩‐n relation does not require calibrated images, the profiles have not had their photometric zero point determined.)
