Ellipticity, e, of ellipses that best fit the spatial distribution of the different stellar populations of ω Centauri (left) and M22 (right) against the semimajor axis, a (lower panels). The upper panels show the difference between the ellipticity profiles as a function of a. The color level indicates the statistical significance of the difference, as indicated by the color bar.
