Measuring time delays: I. Using a flux time series that is a linear combination of time-shifted light curves
Ofer M. Springer, Eran O. Ofek
(Abridged) Several phenomena in astrophysics generate light curves with time delays. Among these are reverberation mapping, and lensed quasars. In some systems, the measurement of…
