Situations....at this moment.
1. BLC tracking -> enabled, but shift correction, time-to-time dt-dx reconstruction are not yet. -> T0 consistency
2. VDC tracking -> enabled, time-to-time dt-dr reconstruction is now in progress. Spline correction is not yet. -> TC consistency
3. PDC tracking -> under construction. -> PA consistency
run-by-run variation of VDC resolution for y-x znd y-z tracking BEFORE dt-dr time-to-time reconstruction and spline correction for COSMIC RAY DATA. Horizontal axis represents the run number and the vertical resolution by mm(sigma). The original dt-dr has been constructed from the cosmic-ray data from run 91 to 116. The resolution of VDC bottom is slightly better, as it used to be the case in E471. If it is reconstructed time-to-time, then the resolution achieved will be below 300 micron WITHOUT spline correction. Some hardware troubles is supposed to have occured for VDCbottom in run 259 and 260.
