Scientific paper

A Fourier series fitting of order 10 to the historical light curve of OJ287 (3648 data points) is presented with correlation coefficient ≡0.73. It is found that the Weierstrass function may be used to imitate the short time scale variability of OJ287. A fractal curve constructed by the function possesses the similar correlation coefficient to the light curve as the regression curve. The authors also calculate the capacity-dimension, information-dimension and correlation-dimension of the light curve. The calculations indicate that their values >1.
