Comparison of classification of X-ray AGN, based on the inclination angle estimated by X-CIGALE and optical / mid-IR colours (Hickox et al. 2017) with respect to the classification using optical spectroscopy.
| Type 1 | Type 2 | |||
|---|---|---|---|---|
| Criterion | Reliability | Completeness | Reliability | Completeness |
| X-CIGALE | 86% | 85% | 47% | 48% |
| X-CIGALE (EB − V = 0) | 95% | 61% | 42% | 75% |
| Hickox et al. | 92% | 50% | 32% | 85% |
Notes. Completeness refers to how many sources classified as type 1 (or 2) based on optical spectroscopy were identified as such by the other two classification criteria. The reliability is defined as the fraction of the number of type 1 (or 2) sources classified by SED fitting or colour criteria that are classified similarly by optical spectra. X-CIGALE completeness for identifying obscured systems rises to 100% if we consider as type 2 systems those that are type 1 based on their inclination angle but have increased polar polar dust. We also quote the percentages when we ran X-CIGALE without the ability to add polar dust (EB − V = 0).
