Upper panel: reconstructed convective blueshift versus T_eff for the stars for which the formula of Allende Prieto et al. (2013) could be applied (stars). The convective blueshift derived from Allende Prieto et al. (2013) for those stars is shown before correction from the wavelength range (red circle) and after correction (green dots). Lower panel: reconstructed convective blueshift versus those derived from Allende Prieto et al. (2013), from the original TSS (stars) and those corrected for the wavelength dependence (diamonds).
