Table 4: Basic kinematical data for the main morphological features in NGC 6309. Angular distance and position angle (PA) are measured from the central star. Radial velocity is measured with respect to the systemic velocity (-32 km s-1) from the emission line indicated in the last column. Uncertainties for the first row apply to the rest.
