Table 4.
Comparison of the sample of AGN candidates selected via our RF5 classifier (1) and the samples of AGN candidates obtained via other selection techniques: the variability-based method from D19 (2); the X/O diagram for the VST-COSMOS sources in the X-ray sample (3); the diagram introduced in Donley et al. (2012) based on the use of MIR colors (4); and the color-magnitude cut used to obtain the catalog presented in Assef et al. (2018) (5).
| RF5 | D19 | X | Donley et al. (2012) | Assef et al. (2018) | |
|---|---|---|---|---|---|
| (1) | (2) | (3) | (4) | (5) | |
| AGN candidates | 302 (77+225) | 271 | 607 | 226 | 64 |
| Matched in this work | – | 240 | 280 | 151 | 44 |
| (RF5 sample plus LS) | (56+184) | (55+225) | (16+135) | (4+40) |
Notes. The first line in the table reports the number of AGN candidates from each selection. The second line reports the number of AGN candidates with a match in the sample of AGN candidates in this work; specifically, in the third line we split this number into the number of matched sources in the sample of RF5 AGN candidates and the number of matched sources in the LS.
