Notes. The complete version of this table is available at the CDS. To estimate the ellipticity, we consistently applied the definition $ϵ=1-\sqrt{{\lambda }_b/{\lambda }_a}=1-b/a$. The columns Θ, Θ_F14, and Θ_M23 represent the angular scale used to measure the ellipticities in their respective papers, measured in degrees. This scale is determined by measuring the angular separation in degrees between the cluster’s center and the most distant star in the sample. This column was not determined for the H10 and C10 samples as the data are not available. For the same reason, the θ₁₄ column for NGC 6626 is left empty. The columns N_PCA, N_F14, and N_M23 represent the number of stars in each sample.
