Fig. 7
Ratio of the likelihoods in the mixed and isotropic models shown for each pulsar . The red colour indicates old pulsars, with τc > 10 Myr. To illustrate the pure effect of the normalization of the velocity distribution, we use the same parameters σ = (76 km s-1, 318 km s-1, 0.32) for both likelihoods. Use of σopt for each model separately gives rise to small shifts.
