Measurements for SW CMa compared against Yonsei-Yale models by Yi et al. (2001) for [Fe/H]  =  + 0.05 and [α/Fe] = 0.0. Evolutionary tracks for the measured masses are shown with solid lines and shaded areas indicating the uncertainty in the location of each track coming from the mass errors. Isochrones from 500 Myr to 900 Myr in steps of 100 Myr are represented by the dashed lines. The best fitting 700 Myr isochrone is drawn with a thicker line.
