The registration of two event characteristics, for example, e (energy) and t (time), gives us a two-dimensional experimental distribution A(e, t), where the extraction of the information of interest stumbles upon the absence of the appropriate parametrical model. A significant advantage of using the autocorrelation spectrometer of delayed coincidences is the possibility to determine the scintillator decay time τ from an energy dependence E = g(t, τ), which, unlike the classical decay time model N(t) = f(t, τ), allows us to establish its parametrical correspondence to some elements of the 2-dimensional data and so to estimate τ by a procedure of the robust fitting which automatically suppresses the impact of parts of data not adequate to the model.
