Scientific paper

This is a proposal to estabilsh a globular cluster distance scale of unprecedented accuracy and reliability, with far-reaching impact on the distance scales of cosmology. Our methd is to compare iternal dipersion proper motions with ground-based determination of the dispersion of the radial velocities {with time already allocated at VLT}. The prospect is a geometrically based distance with an accuracy of better than 2%. Results already in hand for M4 and 47 Tuc, estabilish our ability to make such measurements of proper motions. Our projects has two parts: {1} use archival observation for both epochs when available, {2} The present proposal cover an external field of NGC 2808 and give a second epoch for the cluster NGC6752. Thanks to the ACS features, we will be able to extend the sample in just 2-4 orbits.
