Title: Ca uvby Photometry of Globular Clusters

Abstract: During the last three years we have performed Ca uvby photometry of selected Galactic globular clusters using the CTIO 1m telescope. Our results revealed that Ca uvby photometry provides very powerful method to distinguish multiple stellar subpopulations in globular clusters. We seek to obtain Ca uvby photometry for six faint Galactic globular clusters and four globular clusters associated with the Sagittarius dwarf galaxy using the SOAR. In the past, we failed to obtain reliable color-magnitude diagrams using the CTIO 1m telescope for these objects and the telescope time with the 4m class is badly needed. We also request seven nights of observing time with the CTIO 1m telescope, which will help to finish our survey sooner.
