Diagrams showing distributions of profiles of all six spectral lines in a space of the number of all of the detected peaks on the abscissa versus number of peaks above noise on the ordinate. Affiliations to the individual groups are indicated by different colors and symbols; the legend is located on the right. Sizes of the symbols are proportional to numbers of profiles in the individual positions and these numbers are also shown next to the symbols. Further information on the diagrams is given in the text.
