Table 2.
Demarcation flux densities for number counts from radio AGNs and SFGs at different frequencies and redshift bins.
| Frequency | z < 0.5 | 0.5 < z < 1 | 1 < z < 1.5 | 1.5 < z < 2 | 2 < z < 3 | 3 < z < 4 | 4 < z < 6 |
|---|---|---|---|---|---|---|---|
| 150 MHz | 1614.0 | 854.2 | 667.4 | 633.0 | 466.1 | 416.8 | 102.8 |
| 350 MHz | 1105.8 | 495.9 | 468.0 | 400.8 | 319.6 | 250.1 | 95.6 |
| 1.4 GHz | 502.7 | 208.6 | 153.3 | 111.1 | 80.3 | 57.5 | 15.7 |
| 3 GHz | 213.9 | 95.4 | 70.7 | 58.8 | 41.1 | 26.4 | 9.0 |
| 10 GHz | 83.9 | 37.9 | 27.7 | 20.1 | 16.3 | 9.4 | 3.5 |
| 15 GHz | 68.9 | 31.8 | 18.9 | 15.1 | 11.8 | 6.3 | – |
Notes. All flux densities are in unit of μJy. Due to small number statistics of SFGs at 15 GHz above z ∼ 4, we removed them given they are less robust measurements.
