Based on real data, a new parameterized model of the Main Drift Chamberresponse is proposed. In this model, we tune the ratio of good hits and theresidual distribution separately. The difference between simulation and data intrack reconstruction efficiency reduces from 1% to 0.5%, and the momentumresolution agreement improves significantly.
