| Boötes (err ≤ 0.5) | 881 | −0.04 | 0.26 | 0.82 | −0.007 | 0.084 | 0.82 | 0.96 |

Notes. The statistics are given for each subsample. The experiments all used the same training sample that does not include any spectroscopic quasars from the NDWFS-Boötes field, with the exception of the experiment where the Boötes quasars are included in the training sample.
