Distribution of hit wire on each plane....
A typical TDC channel distribution and dt-dx function.
The residual distribution of the PDC track detection. The tracking condition is 4 single hits on all available 4 planes. The resolution is fairly bad at this moment. Why?
A geometrical mistook was found in the analysis code. Now, the residual distribution is fine. This is obtained for run 68 requiring 4 sequential single hits on all sensitive planes, so that two adjoinning hits on a plane is dropped here.They will be included after plane shift correction -> see, August 29th report.
Subjects to be done on tracking (in order) ....
1. PDC tracking: Enabled, but still some studies needed. Shift correction, time-to-time dt-dx reconstruction are not done yet -
2. VDCbottom relative rotation and position shift determinations by cosmic ray -> Hanaki.
3. BLC relative rotation and position shift by K^+-VTC triggered (K^+ * VTC) run. -> Hanaki.
4. PDC relative rotation and position shift by K^+-VTC triggered (K^+ * charged) run. -> Hanaki.
5. Chamber tracking and single-plane efficiencies and their long-term stability. -> Some efficiencies for some dedicated purpose(or trigger pattern) would be studied after those requirements are recognized.
