CMD comparing our empirical IS (red points) with LMC eclipsing binary stars (black points). Data for well-documented Cepheids in eclipsing binaries are displayed as black symbols. Fits for the blue and red edges of the IS are shown as solid lines (considering a break) and dotted lines (without a break). In addition, evolutionary tracks of 3 to 7 M_⊙ in steps of 0.5 M_⊙ are presented as gray lines.
