Integrated flux densities of the diffuse components in the Perseus cluster.
| LBA (43 MHz) | HBA (144 MHz) | α | |
|---|---|---|---|
| Mini-halo | 126.7 ± 4.2 ± 13.4 Jy | 25.3 ± 0.67 ± 1.41 Jy | −1.34 ± 0.10 |
| GRH | 21.4 ± 1.0 ± 2.4 Jy | 6.34 ± 0.26 ± 0.41 Jy | −1.01 ± 0.11 |
Notes. Integrated flux densities are determined in this work and van Weeren et al. (2024). Uncertainties are twofold: The first uncertainty represents the one reported by the Chi-squared fit (Eq. 1) and is based on the r.m.s. map noise, and the second refers to the systematic 10% flux density scale uncertainty. The error on the spectral indices in this table includes both uncertainties. The uncertainties on the spectral indices without the 10% flux density uncertainties are ±0.035 for the mini-halo and ±0.051 for the giant radio halo.
