Restoring beam sizes assumed for smoothing the emission maps at each observing frequency.
| Beam | FWHM [kpc] | ν [GHz] | Telescope |
|---|---|---|---|
| 5″ × 5″ | 16.6 | 0.15 | LOFAR (a) |
| 5″ × 5″ | 16.6 | 0.65 | GMRT (b) |
| 5″ × 5″ | 16.6 | 1.5 | VLA (c) |
| 20″ × 20″ | 66.3 | 14.25 | Effelsberg (d) |
| 20″ × 20″ | 66.3 | 18.6 | SRT (d) |
Notes. We considered the redshift of the CIZA J2242.8+5301 cluster (z = 0.1921) to quote the corresponding linear length of the full width half maximum (FWHM). The last column mentions the telescope and reference that we considered for our mock radio maps. Note: the radio maps in Loi et al. (2020) quote a resolution of 72″ × 72″ (FWHM = 238.8 kpc) for the Effelsberg observation and 54″ × 54″ (FWHM = 179.1 kpc) for the SRT observation, which are too large compared to our simulation box. Therefore, we have selected a conservative beam of 20″ × 20″ for these two high frequencies.
