Table 7.
Spectral indices, α generated between the LOFAR fluxes and other radio surveys, as presented in Fig. 11.
| Catalogue | Frequency | Matches | α | α |
|---|---|---|---|---|
| (MHz) | within 5″ | Histogram | Gaussian | |
| GMRT | 240 | 192 |  |
μ = 1.25, σ = 0.41 |
| GMRT | 610 | 141 |  |
μ = 0.72, σ = 0.22 |
| FIRST | 1400 | 157 |  |
μ = 0.81, σ = 0.24 |
| VLA | 1500 | 155 |  |
μ = 0.73, σ = 0.20 |
Notes. The median, 16th and 84th percentiles of the offsets have been used to describe the average spectral indices observed. These are from comparisons with GMRT (Tasse et al. 2007), FIRST (Becker et al. 1995; Helfand et al. 2015), and VLA (Heywood et al., in prep.).
