       On plot below it is show distribution of HFT hits from Λc→Kpπ for Ideal (red) and Real (black) geometries 
versus &Phi: and radius.
The shift in acceptance is mainly due to shift of TPC together with HFT with respect to global STAR coordinate system. 
 matrix Tpc2Glob - tr=1  rot=1  refl=0  scl=0

  1.000000   -0.000360   -0.000480    Tx =  -0.238300
  0.000360    1.000000   -0.000100    Ty =  -0.173200
  0.000480    0.000100    1.000000    Tz =  -0.195700
