Profile of the galaxy SDSS 1237661122387969061. Top Left Panel: Image of the galaxy with associated radii indicated by ellipses of different colours: green/yellow for the break positions in the surface brightness profiles of I_E (μ_IE) and H_E (μ_HE) bands, red for the radius at ${\mu }_{I_{\mathrm{E}}}=25\mathrm{mag}{\mathrm{arcsec}}^{-2}$, and blue for the boundary regions of interest in semi-major axis r between [r_b, r_max]. Top Right Panel: Surface brightness profile (μ_IE) versus semi-major axis (r) of the fitted ellipses in the I_E band. Solid lines indicate the fitted models: Single Sérsic model in red, bulge/disc decomposition model in blue, bulge/disc1/disc2 decomposition model in green. The vertical dashed lines indicate in blue the boundary of the region of interest in r where the break may potentially be found, in green the break position, and in red the radius corresponding to ${\mu }_{I_{\mathrm{E}}}=25\mathrm{mag}{\mathrm{arcsec}}^{-2}$. Bottom Left Panel:I_E−H_E colour as a function of the semi-major axis r between [r_b, r_max]. Bottom Right Panel: Surface brightness profile μ_HE versus semi-major axis (r) of the fitted ellipses. The solid lines indicate the fitted models after the radius of the bulge: disc model in blue, disc1/disc2 model in green. The dashed lines indicate in blue the boundary of the region of interest in r where the break may potentially be found and in yellow the break position.
