All observations of HQ Car and VY Car were made at Observatorio Cerro Armazones of the Universidad Catolica del Norte, Chile, between April and May, 2005. The data were obtained using the 16-inch Schmidt-Cassegrain telescope in combination with a CCD ST-9 photometer, with BVIc filters. The BVIc photoelectric observations of EW Sct were obtained using the 75-cm telescope of the South African Astronomical Observatory in April, 2007.
