Caption: Figure 19.

Smoothed spectra of a few rare gems from the MWBP. From top to bottom, the panels show a Carbon Star, a AM CVn type cataclysmic variable, a metal enriched white dwarf with strong Ca lines, a broad absorption line QSO at z = 3.077, and a high-redshift QSO at z = 4.526. The green lines show the noise level in these spectra.
