\IBVSEred{Reduction of CCD frames was made with
a customly developed IRAF\IBVSfm\ package.}

\IBVSfoot{IRAF is distributed by the National Optical Astronomical
Observatories, operated by the Association of the Universities for
Research in Astronomy, inc., under cooperative agreement with the
National Science Foundation}

\IBVSEmethod{The minima times were computed with parabolic
fitting (in case of PV Cas and SV Cam), and Kwee-van Woerden 
method (Kwee \& van Woerden, 1956).}
