Analysis of the Frequency Delay Outburst in the Active Galactic Nucleus using the Discrete Correlation Function

Using methods described earlier (Volvech et al., 2006) we can eliminate certain oscillations in available data. At the same time CrAO´s database contains brightness curves of large number of sources at multiple frequencies. If we determine phase relationship between founded oscillations at different frequencies we can obtain some new intelligence about properties of medium where these oscillations propagate.
