Relation of the a₀ radius versus the break radius of the GCS for each galaxy. The upper row corresponds to the MOND a₀ radius, the bottom row to the Newtonian a₀ radius. The three columns in the horizontal direction correspond to the whole, red, and blue GC (sub)population, respectively. The squares in the first column mark the galaxy sample inspected in this paper, the circles mark those from BSR19. The empty squares denote the suspicious measurements. The diagonal dashed black lines represent the one-to-one relation. The vertical gray dashed lines mark the galaxies that do not have a₀ radii.
