Measured flux density values for the regions labeled A and E in the LOFAR image.
| ν [MHz] | Sν [Jy] | |
| Region A | α | |
| 61.6 | 0.77 ± 0.16 | −1.36 ± 0.09 |
| 74.0 | 0.51 ± 0.12 | |
| 325.0 | 0.075 ± 0.005 | |
| 1360.5 | < 0.0023 | |
| Region E |

|
| 61.6 | 0.96 ± 0.20 | <−2 a |
| 74.0 | 0.32 ± 0.12 | |
| 325.0 | < 0.022 | |
| 1360.5 | < 0.0015 | |
Notes.
Region E is detected in the LOFAR and VLSS images, and the other measurements are only upper limits. Hence, we only show an illustrative polynomial fit in Fig. 6, but do not attempt to derive a spectral index.
