Abstract:
New BVRI broadband photometry and astrometry are presented for the
globular cluster NGC 4147, based upon measurements derived from 524
ground-based CCD images mostly either donated by colleagues or
retrieved from public archives. We have also reanalyzed five exposures
of the cluster obtained with WFPC2 on the Hubble Space Telescope in
the F439W and F555W (B and V) filters.
