The kinematics of 867 galactic planetary nebulae

We present a compilation of radial velocities of 867 galactic planetary nebulae. Almost 900 new measurements are included. Previously published kinematical data are compared with the new high-resolution data to assess their accuracies. One of the largest samples in the literature shows evidence for a systematic velocity offset. We calculate weighted averages between all available data. Of the final values in the catalogue, 90% have accuracies better than 20 km s(-1). We use this compilation to derive kinematical parameters of the galactic differential rotation obtained from least-square fitting and to establish the Disk rotation curve. we find no significal trend for the presence of an increasing external rotation curve. We examine also the rotation of the bulge; the derived curve is consistent with a linearly increasing rotation velocity with l: we find V-b,V-r = (9.9 +/- 1.3)l-(6.7 +/- 8.5) km s(-1). A possible steeper gradient in the innermost region is indicated.
