Demonstration of the approximate equality of the break radii of the GCSs and the a₀ radii of their host galaxies. First row: the ratio of the break radius and the MOND a₀ radius as a function of the break radius. The vertical axis is in the base-2 logarithmic scale, while the horizontal axis in the base-10 logarithmic scale. The horizontal line indicates the ratio of one (the break and a₀ radii are equal). Second row: the same as the first row but for the a₀ radii calculated for the Newtonian gravity. Columns: from left to right, the rows show the data derived for all GCs and for the red and blue subpopulations of GCs.
