Comparison of classes predicted for unassociated sources in the 3FGL catalog with associations in the 4FGL-DR2 catalog.
| 4FGL-DR2class | 3FGL prediction |
Recall | Recall | Recall | ||
|---|---|---|---|---|---|---|
| AGN | PSR | MIXED | (4FGL assoc) | (all agree) | (∑apa > 7) | |
| AGN | 223 | 5 | 30 | 0.86 | 0.94 | 0.92 |
| PSR | 10 | 23 | 12 | 0.51 | 0.67 | 0.61 |
| OTHER | 8 | 6 | 23 | – | – | – |
| Precision(4FGL assoc) | 0.93 | 0.68 | – | |||
| Precision(all agree) | 0.97 | 0.78 | – | |||
| Precision(∑apa > 7) | 0.98 | 0.82 | – | |||
Notes. The classes are predicted using the two-class classification. The precision and recall are calculated using the all-algorithms-agree condition and the 4FGL-DR2 associations (4FGL assoc), or the class probabilities of associated 3FGL sources derived from test samples using either the all-algorithms-agree condition (all agree) or the ∑apa > 7 condition (∑apa > 7). The AGN and pulsar sources are also represented in Fig. 14.
