Comparison between the acceptable ranges for the overshooting parameter from CB2018 (white rectangles) and from our own grids (gray rectangles) assuming the same values of ﹩{f}_{\mathrm{ov}}﹩ for the primary and secondary, and under closely similar conditions regarding ﹩{\alpha }_{\mathrm{MLT}}﹩. Systems are in the same order as discussed previously, and primary and secondary masses in solar units are indicated on the right. The hatched rectangles for χ² Hya and SZ Cen represent the much reduced ranges we obtain by adding the constraint from the temperature ratio (see previous section). For the three lower-mass systems AY Cam, HD 187669, and BK Peg, the hatched areas result from considering the maximum plausible values of ﹩{f}_{\mathrm{ov}}﹩ from theory (Roxburgh 1992) (see Appendix).
