... It shows the distribution in line strength variations contained in each principal component for the clean Coma, noisy Coma, and high redshift data. ... Then, while the coma eigenvalues flatten out, the high redshift eigenvalues continue on the same, more moderate, trend as for the first two until at the fifth component, it joins the already shallow trend of the Coma data. ... Specifically, there are four independent parameters present in the high redshift data, while only two in the Coma data. б  б ...
