  We propose a method that allows to take into account detector resolution in
the partial wave analysis event-by-event fit as a special case. Implementation
of the method is discussed and the applicability of the method is studied for
the $J/\psi \to K^{*\pm}K^{\mp} \to K^+K^-\pi^0$ and $J/\psi \to K_2(1430)^\pm
K^{\mp} \to K^+K^-\pi^0$ decays.
