The events are available as the Dalitz plot with 3160 cells.
The particles are counted as 1- K_s, 2 – pi0, 3 – K- and the data are given as:
3160
s12
s23 Number of real events Number of MC events
s12
s23 Number of real events Number of MC events
……………..
Here s12, s23 are invariant energies squared of
the two meson system (MeV2).
The number of MC events is calculated from very high statistical sample
and smoothed
over the Dalitz plot. The statistical error for
MC is very small and can be neglected.
