| Image | Frequency | Resolution | Median rms noise |
|---|---|---|---|
| Name | [MHz] | [″] | [μJy beam−1] |
| LOFAR-IB | 150 | 0.38 × 0.30 | 50 |
| LOFAR6 | 150 | 6.00 × 6.00 | 100 |
| LOFAR18 | 150 | 18.65 × 14.67 | 210 |
| FIRST | 1400 | 5.40 × 5.40 | 150 |
| VLA* | 3000 | 1.08 × 0.69 | 60 |
| 6000 | 0.29 × 0.23 | 10 | |
| VLASS | 3000 | 2.81 × 2.44 | 150 |
Notes. VLA* represents dedicated observations of one restarted candidate at 3 GHz, presented in Appendix C and one source from the active comparison sample at 6 GHz presented in Jurlin et al. (2021b). Resolutions of the VLASS images varies slightly for the sources in our sample. Here, we list the representative resolution of the sample.
