Notes. Col(1): Name (all newly reported GRGs are marked in bold fonts), Col(2): Angular size (in arc minutes) calculated from the NVSS maps. We choose a size in between the two peak values of hotspots, Col(3): Size of the source in megaparsec, Col(4): Total integrated flux at 1.4 GHz from NVSS map in mJy, Col(5): Total radio power at 1.4 GHz from the total integrated flux in W Hz⁻¹ we assumed a spectral index of 0.75, Col(6): 3 GHz VLASS core flux obtained from Gordon et al. (2021), Col(7): Core radio power at 3 GHz from core flux in W Hz⁻¹ we assumed a spectral index of 0.5, Col(8): The core dominance factor, Col(9): Arm-length ratio (R_θ).
