WebIn most cases, the task is complicated by uneven spacing of data, so that standard cross-correlation methods become useless. Two different methods are most often used: CCF (Gaskell & Spark 1986) and DCF (Edelson & Krolik 1988), which are based on line interpolation of data sets or binning of correlation coefficients, respectively.

The variability analysis of PKS 2155-304

WebNo significant variability was seen in softer (0.1-1 keV) X-ray bands. In the ultraviolet/optical regime the NVA decreased from 9% to 1% as the wavelength increased from 1275 to 6900 A. These data do not probe extreme ultraviolet (1200 A … WebFour methods have been applied to determine the time delay between the two QSO components, giving a mean estimate of \Delta_t = 51+/-4 days (95% confidence level). This is the fourth optical time delay ever measured.

WebDiscrete Correlation Function Method The Discrete Correlation Function (DCF) was intro- duced by Edelson and Krolik (1988). This method provides the correlation between two unevenly sampled time-series data as a function of time lag. WebOct 1, 1988 · Krolik, J. H. Abstract A method of measuring correlation functions without interpolating in the temporal domain, "the discrete correlation function," is introduced.
