Center-to-limb variation of the convective blueshift of Fe I 6301.5 Å (panel a) and Fe I 6302.5 Å (panel b) for different spectral resolutions and line sections. Dashed lines are close to each other or even overlay. The observations are compared with the synthesis for Fe I 6301.5 Å (de la Cruz Rodríguez et al. 2011) and Fe I 6302.5 Å (Cegla et al. 2018).
