Characteristics of the external catalogs with which the emissive point source catalog is cross-matched and results of the cross-matching.
| Survey | Band | Beam FWHM | ∑ (deg−2) | rassoc (arcsec) | P(random) (%) | N. sources |
|---|---|---|---|---|---|---|
| ASKAP low | 887.5 MHz | 25 arcsec | 87.0 | 30.0 | 1.9 | 328 |
| ASKAP mid | 1367.5 MHz | 25 arcsec | 83.3 | 30.0 | 1.8 | 327 |
| ASKAP high | 1655.5 MHz | 25 arcsec | 86.2 | 30.0 | 1.9 | 326 |
| AT20G | 20 GHz (1.5 cm) | 4.6 arcsec | 0.3 | 30.0 | 0.01 | 18 |
| SPT-SZ | 95, 150, 220 GHz | 1.7, 1.2, 1.0 arcmin | 2.2 | 43.2 | 0.1 | 104 |
| WISE | 22 μm | 12 arcsec | 32.6 | 30.0 | 0.7 | 44 |
| SPT-3G | 95, 150, 220 GHz | 1.8, 1.2, 1.0 arcmin | 10.6 | 43.2 | 0.5 | 243a |
Notes. We took into consideration the relative beam sizes and source densities when determining the association radii, ensuring P(random) is ≤2%. The single-band SPT-3G source densities are 5.8, 5.9, and 5.0 sources per square degree for 95, 150, and 220 GHz, respectively. (a)This number reflects sources without counterparts in any of the listed surveys.
