    "abstract": "We complete the introduction of Yano-Koonin-Podgoretskii (YKP)\nparametrization of the correlation function by deriving the corrections to the\ncorrelation radii which arise from releasing the popular smoothness\napproximation and approximation of setting the pair momentum on-shell. We\ninvestigate the definition range of this parametrization and find kinematic\nregions in which the YKP parametrization is inapplicable. These problems\ndisappear if the newly proposed Modified Yano-Koonin-Podgoretskii\nparametrization is used. We then focus on the physical interpretation of the\ncorrelation radii obtained in the different parametrizations. While the\nextraction of the longitudinal source expansion from the YK rapidity is found\nto be rather robust against variations of the source density profiles, the\nextracted emission duration is quite sensitive to such variations and cannot be\nreliably extracted except for the case of extremely long source lifetimes.",
