Scientific paper

Echelle observations of 16 planetary nebulae (PNs) in the O III 5007 emission line are presented which were originally detected in a UK-Schmidt objective prism survey of the outer fields of the Large Magellanic Cloud (LMC). Expansion and radial velocities are derived by a simple Gaussian fitting technique and are used in conjunction with previous data presented to test whether the position angle of the kinematic line of nodes and the systemic Galactocentric velocity of the LMC remain unchanged with the inclusion of this additional outer field information. The results confirm previous values, and the LMC is confirmed to consist of a single disk, and not a dual disk structure.
