Scientific paper

Accurate radial velocities for a sample of 71 planetary nebulae, mostly located in the direction of the Galactic Centre, are presented. Most of the nebulae discussed in this paper are likely members of the Galactic bulge, based on their radial velocity, longitude and derived distance. The data give a large improvement over existing catalogues, doubling the sample of bulge planetary nebulae with well-determined velocities and suggesting that kinematics of the Galactic Bulge can usefully be studied by planetary nebulae. Based on observations obtained at the European Southern Observatory.
