Distribution of the basic properties of the LSBs (blue solid line) and HSBs (green dashed line) in our sample. The average r-band surface brightness within the effective radius and the r-band absolute magnitude are given in the top-left and top-right panels, respectively. The redshift and the effective radius are in the bottom-left and bottom-right panels, respectively. The median values corresponding to each parameter are marked inside each panel in blue and green for the LSBs and HSBs, respectively.
