Heat maps of all data with spectroscopic classifications in SDSS. Comparing this with Fig. 1, we see SDSS has spectroscopic data focused on specific parts of the parameter space. Strict criteria for pure selection of stars (green), QSOs (red), and galaxies (blue) are overplot-ted. These are listed in Table 2. The fit-parameter panel also includes a black line showing the Schmidt et al. (2010) QSO selection.
