A) Ellipticity, B) centroid (), C) fourth-order Fourier cosine moment, and D) position angle radial profiles of our sample galaxies. All radial profiles are normalized to the effective radius in the abscissa axis. Blue, green, and red solid lines refer to BGGs with MKs ≥ − 26, − 26 < MKs < − 27, and MKs ≤ − 27, respectively. Both the centroid and position angle profiles were reported to their values at re. The radial profiles are plotted for larger radii than the corresponding PSF FWHM.
