M.A.Burlak, I.M.Volkov and N.P.Ikonnikova Absolute parameters and period variation in a semidetached eclipsing variable V2247 Cyg Files all_{filter}.txt contain our observations of V2247 Cyg obtained with AZT-5 telescope of Sternberg Astronomical Institute(SAI) Crimean station. All data were transformed into standard Johnson-Cousins photometric system with the help of procedure described in the article. First column contains Julian heliocentric date(JDhel) referred to the middle of exposition. Second column contains the magnitude of the star. Files Liuty_{filter}.txt contain our observations of V2247 Cyg obtained with Zeiss-600 reflector of SAI Crimean station and one-channel photometer with photomultiplier EMI9789 constructed by V.M.Liuty. All observations were reduced to Johnson photometric system. The first column of the tables contains JDhel referred to the middle of exposition, the second - magnitude of the star. Please, feel free to use the data selected in these files only the paper (M.A.Burlak, I.M.Volkov and N.P.Ikonnikova: 2018, Contrib. Astron. Obs. Skalnate Pleso 48, Vol. 4, 1) should be quoted in each official using of the file or its part.
