Notes. The columns are (1) observing frequency, (2) Peak DCFs and uncertainties in P2, (3) time lags (τDCF) and uncertainties of the DCF computed between the γ-ray light curve and those in other frequency bands in P2, (4) Peak DCFs and uncertainties in P3, and (5) time lags (τDCF) and uncertainties of the DCF computed between the γ-ray light curve and those in other frequency bands in P3. Time lags are marked with a star symbol (⋆) when the peak DCF is above the 99.7% confidence level.
