uvby photometry of 6 eclipsing binaries

Within the long-term Copenhagen Binary Project, we aim to obtain high-quality light curves and standard photometry for double-lined detached eclipsing binaries with late A, F, and G type main-sequence components, needed for the determination of accurate absolute dimensions and abundances, and for detailed comparisons with results from recent stellar evolutionary models.

Between March 1985 and July 2007, we carried out photometric observations of AD Boo, HW CMa, SW CMa, V636 Cen, VZ Hya, and WZ Oph at the Stromgren Automatic Telescope at ESO, La Silla. We obtained complete uvby light curves, ephemerides, and standard uvby{beta} indices for all six systems.
