Fig. 6.
Azimuthally-averaged surface brightness profiles and colour profiles of the group members. Top panels: azimuthally-averaged surface brightness profiles of HCG 86A, HCG 86B, HCG 86C and HCG 86D in VST g (blue), r (green), and i (red) bands. Bottom panels: g − r (black) and r − i (violet) colour profiles of HCG 86A, HCG 86B, HCG 86C, and HCG 86D. The points at 6.67 arcmin (i.e. Rlim in the g band) in each panel correspond to the integrated colours of the IGL component.
