The AMIGA project adopted the Catalogue of Isolated Galaxies (CIG: Karachentseva 1973) as a starting point. In our previous works we identified several CIG galaxies failing Karachentseva’s criterion, hence motivating us to carefully revise the isolation of the CIG members. Hence we use this sample as a starting point to refine and perform a better quantification of its isolation properties.

Close-up view of the distribution of galaxies around CIG 714 (the bottom-right galaxy) in over-plotted DSS image. The detected galaxies are marked with blue ellipses, the stars are marked by red ellipses. The objects too small or to faint to be assigned a type are shown by the green ellipses. The plate defects were removed from our object extraction.
