Notes. The subscripts ‘SCl’ and ‘GRG’ indicate foreground supercluster and background GRG properties, respectively. The columns RA, Dec, and z are the right ascension, declination, and redshift, respectively. Cat-ID refers to the ID source number from the catalogue of O’Sullivan et al. (2023). RRM_GRG stands for residual rotation measure (the value of rotation measure after correcting for the galactic magnetic field contribution), ΔL_∥, SCl is the path length covered by the polarised light (from the background GRG) inside the supercluster, ΔL_⊥, SCl is the approximate projected length of the polarised emission from the background GRG on the supercluster, and Δz_SCl is the redshift width of the supercluster. B_∥, SCl is the estimated magnetic field in the supercluster for n_e1 and n_e2 corresponding to the n_e values of 10⁻⁶ cm⁻³ and 10⁻⁷ cm⁻³, respectively (see Sect. 5 and Appendix D for further details).
