The first half of a compilation plot provided by CorrSim. Top, Middle: 100 s, 10 s, and 2 s segments of the produced light curves (Band A, blue, top panels; band B, red, bottom panels). The dashed lines represent the ranges of the insets. Bottom: Model (left) and simulated (right) correlation functions (Band B versus band A, i.e. a peak at positive lags shows band B lagging band A), with the latter also showing the range over which it was averaged. The model correlation function was calculated from the input coherence, power spectra, and lags (see Fig. 5, while the reproduced correlation function was produced from the light curves.
