Fractions of obscured (with HR > − 0.4) X-ray AGN with respect to their mid-infrared (24 μm) to optical flux ratio and RC − K colour.

| f24 μm/fRC > 100 | 38/56 (67.9%) | 18/34 (52.9%) |
| f24 μm/fRC < 100 | 13/57 (22.8%) | 33/63 (52.4%) |
| RC − K > 4 | 40/55 (72.7%) | 36/64 (56.3%) |
| RC − K < 4 | 11/58 (19.0%) | 15/33 (45.5%) |
Notes. Here an RC − K = 4 division is used to denote optically obscured and unobscured objects. This is a more modest limit than the RC − K = 5 used in this paper and elsewhere to select EROs.
