Expected numbers of sources among the unassociated 3FGL and 4FGL-DR2 sources.
| Catalog | Classification | AGN | PSR | OTHER | MIXED |
|---|---|---|---|---|---|
| 3FGL | Two-class | 599 | 111 | – | 300 |
| Two-class corr | 580.0 | 97.0 | 56.4 | 276.5 | |
| Three-class | 587 | 53 | 69 | 301 | |
| 4FGL-DR2 | Two-class | 878 | 162 | – | 627 |
| Two-class corr | 826.2 | 134.5 | 140.4 | 565.9 | |
| Three-class | 739 | 64 | 274 | 590 | |
Notes. Expected numbers of AGNs, pulsars, and OTHER sources as well as sources with mixed classifications are derived with the two-class (Sect. 4) and three-class (Sect. 5) classification. The “two-class corr” row shows the correction of the two-class classification prediction due to the presence of OTHER sources among the unassociated ones (see Sect. 4.1 for details).
