Scientific paper

Photometric UBV differential observations of three short-period eclipsing binaries (RW Dor, EZ Hya, and V701 Cen) are presented. New times of minimum light and improved linear ephemerides are given. Analysis of the trends of the differential color curves show that RW Dor cannot be considered a normal W UMa system, since its d(B-V) at minima is redder than at maxima. The curves for EZ Hya do not show remarkable variations, while V701 Cen shows a d(B-V) higher at primary minimum that at maxima.
