Fig.2 Dalitz x_{D} = (m_{e+e}/m_{pi0}) for fullyreconstructed Dalitz decay candidates after normalization mode analysis cuts. Monte Carlo prediction using the world average form factor slope parameter is overlaid.

Fig.3 Positronelectron invariant mass for pi^{0}>e^{+}e^{} signal candidates passing all other cuts. The points with error bars are data; the solid histogram is background MC.

Fig. 4 Ratio of data to MC distribution of m_{e+e} in the sideband region below the signal peak, where the MC was normalized to the number of fullyreconstructed Dalitz decays. The dotted line indicates the ratio over the entire region.
