Solar convective blueshift as a function of T_1/2 at the line cores. Only lines that could be cross-matched with the VALD3 line list are displayed. The markers of lines from the final selection are color-coded, and the line depth is shown in the color bar. The other lines are shown in gray. The gravitational redshift of RV_grav= GM/Rc, where M and R are the solar mass and radius, has been subtracted.
