Comparison between the measured surface-brightness profiles of NGC 4123 in the B band reported by Weiner et al. (2001; solid line), by Micheva et al. (2013; long dashed line), and obtained here (short dashed line). The X-axis shows the galactocentric radius in arcmin, and the Y-axis the surface brightness in mag arcsec-2. The arrow indicates the optical isophotal radius R25.
