Surface brightness, ellipticity, and PA radial profiles of MATLAS-2019. The left panel shows the u-band (blue), g-band (teal) and r-band (red) surface brightness profiles as a function of the semi-major axis obtained with a fixed centre and ellipticity (ϵ = 0.07). The surface brightness profiles have been corrected from extinction. The right panel shows the position angle (top) and ellipticity (bottom) profiles from letting the parameters of the fit vary freely.
