// DedxPID package:  particle identification with dE/dx 
// read original chi from DstDedx, 
// make beta*gamma = p/m  and dip angle cos(theta) dependent correction   
// 
// In 1st version, only the momentum dependent is taken into account
// The corrections are made by: M.Yang, M.S. Chen, L.L. Wang, J.Y. Zhang and Y.Z. Sun
