Comoving correlation length for different flux density thresholds at the central LoTSS frequency of 144 MHz and clustering parameter ϵ. For comparison a selection of measurements from the literature are shown. The result of Peacock & Nicholson (1991) uses bright radio galaxies at z < 0.1 and does therefore not depend on the clustering evolution (ignoring any factors of 1 + z, they implicitly use the comoving clustering model), thus applies to any value of ϵ. The analysis of Mazumder et al. (2022) uses observations at 325 MHz and distinguishes AGNs and SFGs. We show their results for AGNs. The radio sources from Lindsay et al. (2014) (FIRST at 1.4 GHz) and Hale et al. (2024) (LoTSS-DR2 at 144 MHz) are mostly AGNs.
