Residuals of the mean spectrum of extreme emission galaxies [classification angles in the range (−60, −40, 120, 135)] with the KL‐reconstructed spectrum using (a) 3, (b) 4, (c) 5, and (d) 10 eigenspectra. The insets are the enlarged regions of the continuum levels; in each case the solid line is the mean spectrum and the dotted line is the mean of the KL‐reconstructed spectra. The spectra are normalized at 5500 Å.
