Detection efficiency (number of detected galaxies over number of generated ones in the same bin) of our detection algorithm is shown color-coded such that red means more efficient, while blue less efficient. The efficiency is plotted for effective radius (R_e, the pixel scale is 0.21 arcsec pix⁻¹), axis ratio (b/a), and Sérsic index n, as function of mean effective surface brightness, without (top row) and with (bottom row) minimum size limit. The white lines show the 50% detection efficiency limit.
