Star/Quasar Classification ROC Curves
-------------------------------------
Figure 9.18

The left panel shows data used in color-based photometric classification of
stars and quasars. Stars are indicated by gray points, while quasars are
indicated by black points. The right panel shows ROC curves for quasar
identification based on u - g , g - r , r - i , and i - z colors. Labels
are the same as those in Figure 9.17.
