Fig. 4

Contours of ℒ(σ) in three σ1,σ2 planes with fixed w, for the model with two isotropic Maxwellians. Contours of constant Δℒ(σ) (Eq. (12)) are shown for values 1 and 4, in each plane, The best solution is indicated with •. Top: all pulsars. σopt = (77 km s-1, 321 km s-1, 0.42). Below: pulsars with τc < 10 Myr. σopt = (83 km s-1, 335 km s-1, 0.32).
