The events are available as the acceptance corrected Dalitz plot.

The particles are counted as 1- pi, 2-eta, 3-pi and the data are given as:

1752

s12 s23 s13 Fraction_of_cell_aria Events Error Number of sells

s12 s23 s13 Fraction_of_cell_aria Events Error Number of sells

……………..

Only half of the Daltz plot is given. If Number of sells =2 then the sell should be taken twice with permutation of pions. If Number of sells=1 the sell is on the diagonal and

must be taken only one time.

The s12, s23 and s13 are invariant energies squared of the two meson system (MeV²)

and Fraction_of_cell_area is the ratio of cell area to area of a largest cell.

For these data Fraction_of_cell_area=1: all cells at the boundary are taken out.

The background level for these events is less then 1%.
