Abstract:
UBV CCD photometry has been obtained for 14 OB associations in the
Magellanic Clouds using the University of Toronto's 0.6m telescope
and the Carnegie Institution of Washington's 1.0m reflector, both on
Las Campanas, Chile. The data are presented and used to construct
color-magnitude diagrams for the purposes of investigating the
massive-star content of the associations.
