Upper panel: rest frame velocity of all the PN in NGC 5128 with an observed velocity, plotted versus position along the major axis (PA 35°). The systemic velocity of the galaxy is taken as 539 km s^-1. Blue points are from the FLAMES SV and open time observations; red points for the literature values from Table 11. Lower: as for the upper panel, but plotted against offset along the minor axis (PA 125°).
