FIG. 2.

Contour plots of the scaling factors from Eqs. (15)–(18) (A block). The solid line shows where ${\chi }_{2,\pm \mathrm{1,10}}^{\text{CSA,A}}={\chi }_{2,\pm \mathrm{2,10}}^{\text{CSA,A}}$. The dashed line shows where ${\chi }_{2,\pm \mathrm{1,20}}^{\text{DD,A}}={\chi }_{2,\pm \mathrm{2,20}}^{\text{DD,A}}$. The additional scaling factors [Eqs. (19)–(23)] are not shown. Gray Xs mark the (a, b) combinations that are used in this work.
