Notes. The colour c is derived using optical – 4.5 μm magnitude where we use the i- (or I-) band in ELAIS-N1 and Boötes, and the r-band in Lockman Hole. The LR thresholds (LRth) derived from the intersection of the completeness and reliability function (see Appendix C) and used for selecting genuine cross-matches are also listed. Scaled (by excluding sources in region of around stars, i.e. FLAG_CLEAN ≠ 3) total Q0 (c) values are also listed.
