Astrometric criteria based on the Galactic latitude (b) and their corresponding completeness, purity, and stellar contamination.
| Galactic latitude | Astrometric criteria | Completeness | Purity | Stellar contamination | Source number in bin |
|---|---|---|---|---|---|
| 0° ⩽ |b| < 20° | 84.35% | 99.22% | 0.78% | NQ = NS = 8901 | |
| 20° ⩽ |b| < 30° | 97.83% | 96.07% | 3.93% | NQ = NS = 93 119 | |
| 30°⩽ |b| < 45° | 98.07% | 94.88% | 5.12% | NQ = NS = 198 068 | |
| 45° ⩽ |b| < 60° | log f0pm ⩾ −3 | 98.12% | 94.51% | 5.49% | NQ = NS = 226 976 |
| 60° ⩽ |b| < 75° | log f0plx ⩾ 2 | 98.16% | 94.21% | 5.79% | NQ = NS = 143 273 |
| 75° ⩽ |b| ⩽ 90° | 98.05% | 94.58% | 5.42% | NQ = NS = 34 605 | |
| Total | 97.90% | 94.81% | 5.19% | NQ = NS = 704 942 |
Notes. The Galactic latitude range of 0° ⩽ |b| < 20° is the Galactic plane. Due to the lack of confirmed quasars within it and the abnormal purity and stellar contamination, the final astrometric filtering on the astrometricCAT sources within this region was not performed. The last column lists the numbers of quasars (NQ) and stars (NS) in each sky region bin prior to astrometric filtering.
