Top panels: g − i colour map of FCC 167 inside 4.5 × 4.3 arcmin from the centre (left panel) and a zoom towards the nuclear regions (right panel) for 2.6 × 1.8 arcmin. The g − i levels are shown in the colour bar. Bottom panel: azimuthally-averaged g − i colour profile as function of the semi-major axis by the fit of the ellipses. The vertical long-dashed line indicates the transition radius at R ∼ 3 arcmin, between the disc and the outer stellar exponential halo (see Sect. A.7).
