Notes. Column 1 report the name of the HCG 86 group members. In Col. 2 is given the morphological type. In Cols. 3 and 4 are listed the celestial coordinates of each group member. In Col. 5 is listed the heliocentric radial velocity. Velocities for HCG 86 A, HCG 86 B and HCG 86 D are from de Carvalho et al. (1997), while that for HCG 86 C is from Jorgensen et al. (1995). In Cols. 6 and 7 are reported the total magnitude and the total magnitude at the transition radius in g band, while in Cols. 8 and 9 list the effective radius in the g band, in arcsec and kpc respectively. The average g − r and r − i colours, derived up to transition radius, are listed in Cols. 10 and 11. Magnitudes and colours were corrected for Galactic extinction using the extinction coefficients provided by Schlafly & Finkbeiner (2011).
