Result from the artificial dwarf galaxy test with MTObjects showing the recovery rate (color scheme) as a function of total apparent magnitude m_r and half-light radius r_eff. The red line indicates the lower surface brightness cut (22 mag arcesc⁻²), the white line the estimated completeness at 50% (27.3 mag arcesc⁻²), and the dashed white lines the 75% (26.7 mag arcsec⁻²) and 25% (27.7 mag arcsec⁻²) limit. The black dot indicates the known dwarf galaxy Sculptor-dE1.
