LMC Washington CMT1 photometry of star clusters

The data base was exploited in order to search for new star cluster candidates, to produce cluster CMDs cleaned from field star contamination and to derive age estimates for a statistically complete cluster sample. We confirmed that 146 star cluster candidates are genuine physical systems, and concluded that an overall ~30 per cent of catalogued clusters in the surveyed regions are unlikely to be true physical systems.

We did not find any new cluster candidates in the outskirts of the LMC (deprojected distance >~8{deg}). The derived ages of the studied clusters are in the range 7.2<log(t[yr^-1^])<=9.4, with the sole exception of the globular cluster NGC 1786 (log(t[yr^-1^])=10.10). We also calculated the cluster frequency for each region, from which we confirmed previously proposed outside-in formation scenarios.
