Central Proper-Motion Kinematics of NGC 6752

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.
