Abstract

We build differential-reddening maps for 66 Galactic globular clusters(GCs) with archival Hubble Space Telescope WFC/ACS F606W and F814W photometry. Because of the different GC sizes (characterized by the half-light radius Rh) and distances to the Sun, the WFC/ACS field of view (200 arcsec × 200 arcsec) coverage (Robs) lies in the range 1 < 15 for about 85 per cent of the sample, with about 10per cent covering only the inner (Robs
