Comparison of the angular two-point correlation function estimated from the LoTSS-DR1 value-added source catalogue for radio sources with redshift information and theoretical expectations (solid lines) for the best-fit ΛCDM cosmological parameters from Planck, generated using CAMB SOURCES with Halofit and b(z) from Eq. (28). The integral constraint w_Ω is computed for the expectations and subtracted from them. Positive values are shown with full symbols and solid lines, whereas negative values are shown with open symbols and dashed lines.
