Central proper-motion kinematics of NGC 6752.

Abstract (from CDS):

We present proper motions derived from Wide Field Planetary Camera 2 (WFPC2) imaging for stars in the core of the peculiar globular cluster NGC 6752. The central velocity dispersion in both components of the proper motion is 12 km.s–1. We discuss the implications of this result, as well as the intrinsic difficulties in making such measurements. We also give an alternative correction for the 34-row problem in the WFPC2 CCDs.
