Check dE/dx for CuCu22 in run V.

I have checked status of dE/dx for CuCu22 in run V with sample /star/data43/reco/cu22ProductionMinBias/FullField/P05if_dedx/2005/* with calibration done for CuCu200. In general plots look o.k. No additional dE/dx calibration is necessary.

Resolution

is better than CuCu200 one
<
There is an systematic shift within 1% in dE/dx versus track length in TPC
dE/dx plots versus momentum look o.k.
