We used multi-epoch adaptive optics assisted near-infrared observations of the central parsec of the Galaxy obtained with NACO/CONICA at the ESO VLT. Stellar positions were measured via PSF fitting in the individual images and transformed into a common reference frame via suitable sets of reference stars. We measured the proper motions of more than 6000 stars within about 1pc projected distance of the supermassive black hole Sagittarius A*. The table contains for each measured star its projected distance from Sagittarius A*, its offsets in right ascension and declination from Sagittarius A* along with the corresponding uncertainties, its proper motion and the corresponding uncertainty in right ascension and declination, the Ks-band magnitude and the corresponding uncertainty, and its classification as early type in case such a classification exists.
