Local (four upper panels) and disc-integrated (bottom panel) Nal D2 line profile at 5889.95 Å in the air, for a model star simulated with EVE under various conditions. Case a: constant local line profiles over the stellar disc. Case b: impact of fast stellar rotation on local line profiles. Case c: impact of CLVs on local line profiles. Case d: impact of CLVs and fast stellar rotation on local line profiles. Only a few red-shifted local spectra are shown for the sake of clarity in cases c and d. Local intensity spectra were taken for μ positions along the stellar equator to sample larger radial velocities.
