Cumulative radial distributions of five subpopulations of stars in the core of NGC 6522. Top left: Red giants (solid) vs. HB stars (dashed). Top right: Red giants (solid) vs. SHB stars (dashed). Bottom left: Red giants (solid) vs. AGB stars (dashed). Bottom right: Horizontal‐ branch (solid) vs. SHB (dashed) stars. The K‐S test probability that the two subpopulations in a frame of this figure have the same radial distribution is given in each frame.
