Detector:Apogee ALTA U47 CCD camera, Peltier cooling, E2V CCD47-10 chip, 15 ′ × 15 ′ FOV, 1024 × 1024 pixels.Apogee ALTA U42 CCD camera, Peltier cooling, E2V CCD47-10 chip, 15 ′ × 15 ′ FOV, 2048 × 2048 pixels.ST237 camera, Peltier cooling, TC237 chip, 11 ′ × 8 ′ FOV, 640 × 480 pixels.STL1001E camera, Peltier cooling, KAF-1001E chip, 28 ′ × 28 ′ FOV, 1024 × 1024 pixels. Method of data reduction:Reduction of the CCD frames was made with C-MUNIPACK software (http://c-munipack.sourceforge.net/). Method of minimum determination:The minima times were computed with the Kwee -van Woerden method (Kwee & van Woerden, 1956).
