Plots on various CMDs of a 2.3 Gyr isochrone for [Fe/H] = −0.40, [α/Fe] = 0.0, and Y = 0.26 that employ bolometric corrections, which were computed on the assumption of E(B − V) = 0.0, 0.2, 0.4, and 0.72. The dashed curves indicate where the same isochrones would be located if it is assumed that the reddening is independent of spectral type. In these cases, the R_λ values appropriate to ≈7300 K, nearly unreddened TO stars were assumed to be valid for all values of E(B − V) and applied to all of the stellar models along the isochrone; see the text for details.
