How to Measure Energy-Dependent Lags without bins in Energy or Time?

How to Measure Energy-Dependent Lags without bins in Energy or Time?. The data: time and energy tagged -- t i E i i = 1, 2, ... , N Usual approach : - bin the data in both time and energy - find peak in cross-correlation function (across E bands) Entropy approach

Abstract

Light curves of UM673 A&B in 2003-2008. Since quasar components change their brightnesses in a similar way, the observed variations are most probably connected with the intrinsic quasar variability and can be used to measure the time delay between images of UM673.
