For Bjorken models with gradual freeze out, the resulting post freeze out momentum distribution practically does not depend on the layer thickness. Using such a model we calculate the pion correlation function produced in Pb+ Pb central collisions The correlation function is in qualitative agreement with other publications but our model allows us to perform a more detailed study of how this affects the final observables. We also find a good agreement with experimental data from ALICE and we deduce that long freeze out averaged correlation functions are more similar to experimental data than sharp freeze out.
