Distribution in the sky of the galaxy members listed in the catalogue of the AMICO group G52 (left panel). Objects in the catalogue with P_assoc < 0.7 are plotted with grey dots. The galaxies with P_assoc (≥0.7) are shown with circles that are coloured according to their P_assoc. The most massive galaxy and the galaxy with the highest P_assoc are marked by a red and a cyan cross, respectively. The group centre is also marked with a large black cross. Right panels: distribution of P_assoc in the catalogue, the stellar mass, absolute magnitude in the r band, and redshift. The position of the BGG is marked with a red vertical line. The distribution of the galaxy members (P_assoc ≥ 0.7) is shown with the black histogram.
