Planetary Nebulae: General, Galaxy: Center, Galaxy: Kinematics And Dynamics

Scientific paper

Radial velocities of 76 objects in the direction of the galactic centre based on 153 spectra (range 3500-7350A) are presented. Using the dispersion 45-100A/mm the internal error of the mean object is 12km/s depending on the number of lines used, whereas the external error was derived to be +/-4.7km/s. The excitation classes of the nebulae were also estimated.
