Аннотация:A total of 9128 B-, V -, and I c -band photometric measurements were acquired for 64 classicalCepheids in 1982–2014. For these stars, 1384 times of maximum light are determined and O–Cdiagrams constructed based on available photoelectric and CCD observations. The data are used tocompute the current ephemerides and the normalized Fourier coefficients (cosine expansion), whoseanalysis confirmed that all the 64 variables were correctly classified as classical Cepheids.
