      abstract     = {A method is reported to determine the phase and amplitude
                      of sinusoidally modulated event rates, binned into four bins
                      per oscillation, based on data generated at the resonant
                      neutron spin-echo spectrometer RESEDA at FRM-II. The
                      presented algorithm relies on a reconstruction of the
                      unknown parameters. It omits a calculation-intensive fitting
                      procedure and avoids contrast reduction due to averaging
                      effects. It allows the current data acquisition bottleneck
                      at RESEDA to be relaxed by a factor of four and thus
                      increases the potential time resolution of the detector by
                      the same factor. The approach is explained in detail and
                      compared with the established fitting procedures of time
                      series having four and 16 time bins per oscillation. In
                      addition the empirical estimates of the errors of the three
                      methods are presented and compared with each other. The
                      reconstruction is shown to be unbiased, asymptotic and
                      efficient for estimating the phase. Reconstructing the
                      contrast increases the error bars by roughly $10\%$ as
                      compared with fitting 16 time-binned oscillations. Finally,
                      the paper gives heuristic, analytical equations to estimate
                      the error for phase and contrast as a function of their
                      initial values and counting statistics.},
