Scientific paper

The use of spectra with resolutions of 6, 9, 12, and 15 km/s to produce maps of abundance inhomogeneities on the surfaces of stars is studied. It is assumed that the spectra have a high SNR, are free from blends, and that the inclination of the axis of rotation and the locations of surface features are favorable. Numerical studies of the Fe II 4923 A line showed that, for v sin i greater than about 30 km/s, good maps of surface features can be expected from spectra with resolutions of 6 km/s or better.
