Fig. 7
Fractional difference in radius as a function of a) metallicity and b) effective temperature for the 20 stars with radii based on parallaxes. The symbols give the fractional difference between the stellar radius determined from the parallax (SA12), the stellar radius determined from AME, and the one determined using the BaSTI grid in turn. (We made the difference fractional by dividing it with the radius from AME.) The individual errors on the radii have been added in quadrature. The dashed line marks a difference of zero.
