Notable realisations Case2 (orange) and Case3 (red). Top panel: GWB spectra. The dashed black line represents the f−2/3 trend. The sensitivity curve is the one presented in The International Pulsar Timing Array Collaboration et al. (2023). The central and bottom panels show corner plots of the GWB parameter posteriors inferred from the analysis using nine (central panel) and four (bottom panel) frequency bins for the GWB recovery.
