Posterior distributions of the CGW parameters, inclination angle, chirp mass, luminosity distance, frequency, initial phase, and polarization angle, recovered with a CGW-only model (considering both Earth and pulsar term) applied to the three GWB only datasets. The inset sky map shows the reconstruction of the (fake) CGW sky location. The black stars in the sky map represent the positions of the 25 EPTA pulsars, while the two red dots are the Virgo and the Fornax clusters, there as a reference.
