Notes. Comparison of the main outputs of the GWB analysis obtained with five simulated datasets (selected according to the agreement with the HD S/N of the real EPTA DR2) and the real data. The main outputs are the median of the noise marginalised optimal statistics HD S/N, the median of the marginalised posterior distribution of the slope and the ampliutde of the GWB, the confidence interval corresponding to the nominal value γGWB = 13/3 and the degeneracy coefficient (JSD). The HD S/N and the JSD values are shown also for the synthetic dataset DR2full + IPTA investigated in Sect. 3.2.
