(a) Values of the overshooting parameter for the primary and secondary of OGLE-LMC-ECL-CEP-0227 that give acceptable fits to the observations within our 5% limit on the age difference (dots). The full ranges we find are shown by the crosshatched area. The red diagonal line in this and subsequent figures marks the full ranges in ﹩{f}_{\mathrm{ov}}﹩ reported by CB2018. Labels indicate the adopted system metallicity and the range of values explored in our grids for ﹩{f}_{\mathrm{ov}}﹩ and ﹩{\alpha }_{\mathrm{MLT}}﹩. (b) Same as panel (a), restricted to ﹩{\alpha }_{\mathrm{MLT}}=2.00﹩.
