Ca II IRT-2 line profile of HD 82106 (K3 V, v sin i = 3.0 km s−1) at three different spectral resolutions: RAVE R=7500; STELLA R=55 000; and PEPSI R=250 000. The spectra are on the same scale but shifted in intensity for better viewing. The vertical shaded area indicates the 1-Å integration window for the line-core fluxes.
