Example synthetic profiles in LTE (dashed) and NLTE (solid) of the Li resonance line, computed with the same abundance (A(7Li) = 2.0, 6Li / 7Li = 0.0, vrotsini = 0.0) for the model of HD 140283. Also shown is an LTE line profile interpolated to meet the same equivalent width as the NLTE line (dotted). More absorption appears in the red wing relative to the blue in NLTE due to strongly differential effects in granules and inter-granular lanes.
