The distribution of ﹩{\rm{\Delta }}a/{a}_{\mathrm{core}}﹩ vs. ﹩{\rm{\Delta }}b/{b}_{\mathrm{core}}﹩ of the sample clusters. The color shade of the solid circles indicates the logarithmic ages (years) of the sample clusters. The size of the symbol is proportional to the number of sample cluster members.
