The resonant substructure of the decay D0→K 0sηπ0 was discussed using Dalitz technique. The study also find dominant contributions from a 0(980)K0s and K*(829)η intermediate states. Using an isobar model averaging of four model was made for additional components and find the amplitude, phase and fit fractions. It was shown that the amplitudes and phases were extracted from the fit, derived from fit fraction which integrates its matrix elements amplitude square and allow phase space division.
