Notes. These data have been split-tabulated according to their respective data sets, where DS1 is solely comprised of optical data, and DS2,3 respectively include GALEX and WISE photometry for each source. N DS is the number of objects from the data set. Precision Q, Recall Q, Precision S, and Recall S are the precision for quasars, recall for quasars, precision for stars, and recall for stars, respectively. N Quasars is the number of objects classified as quasars from the data set, and % Quasars is the percentage of those classified quasars from all the objects of the data set.
