Spatial distribution and star cluster formation of the LMC bar region

New integrated UBV data of star clusters projected on the LMC bar region have been obtained at the Cerro Tololo Inter-American Observatory (Chile) and at the Complejo Astronómico El Leóncito (Argentina). The sample includes 98 clusters, 66 of them being previously unstudied objects. Most of the obse...
