Nominal distance from the Galactic plane z′ = sinb/ϖ′, range sinb/ (ϖ′ ± σ_ϖ), as a function of longitude. The blue points indicate pulsars nominally moving away from the plane, that is z′ and have the same sign; the red points are pulsars nominally moving towards the plane. The grey band indicates the scale height of 50 pc of O-stars. The numbers refer to the sequence number in Table D.1. Numbers 16 at z′ = 1.6 kpc and 17 at 5.5 kpc, respectively, are outside the frame, and both are moving away from the Galactic plane.
