Abstract:
We present BVI CCD photometry for more than 10,000 stars in the
innermost region (0.3'<r<~4') of the globular cluster M 3. When added
to the previous photographic photometry by Buonanno et al.
(1994A&A...290...69B) reaching as far as r~7', this results in an
homogeneous data-set including about 19,000 stars measured in this
cluster, which can be now regarded as one of the main templates for
stellar population studies.
