\IBVSEdet{SSP-5 photometer including Hamamatsu R4457 photomultiplier and High-Speed Three-Channel Photometer including Hamamatsu R1436P photomultiplier. }

\IBVSEred{The differential magnitudes were corrected for atmospheric extinction and the observing times were reduced to the Sun's center. }

\IBVSEmethod{The times of minima were computed using the Kwee and van Woerden method (Kwee and van Woerden 1956) as implemented 
in AVE\footnotemark \,.}
