Abstract

We describe the development of a fitter to reconstruct $\nu_\mu$ induced Charged-Current single $\pi^0$ (CC$\pi^0$) events in an oil Cherenkov detector (CH$_2$). These events are fit using a generic muon and two photon extended track hypothesis from a common event vertex. The development of ring finding and particle identification are described. Comparisons between data and Monte Carlo are presented for a few kinematic distributions.
