Ellipticity epsilon and surface brightness μ V along the major axis of NGC 4762 measured by fitting ellipses to the isophotes in the ACS and SDSS g-band images. We used the transformation V = g + 0.320 − 0.399( gz) from KFCB and the galaxy color gz = 2.076 from F2006. All magnitudes and colors are VEGAmag. The dashed curves show a decomposition of the profile inside the fit range (vertical dashes across the profile). The bulge, bar, lens, and disk are represented by Sérsic functions with indices n given in the figure. Their intensity sum (solid curve) fits the data with an rms of 0.033 V mag arcsec −2.
