Comparison of representative peculiar spectra (colored in the same way as in Fig. 19) to the solar spectrum (gray). An approximate normalization was performed by manually setting the continuum. The wavelength ranges were chosen such that the respective reason for peculiarity is illustrated best. The GES identifiers of the stars are (from upper left to lower right) 08100380-4901071, 18184436-4500066, 23001517-2231268, and 08090542-4740261.
