PDC analysis.

PDC Larm upsetream plane hit-channel PDC Larm downsetream plane hit-channel PDC Rarm upsetream plane hit-channel PDC Rarm downsetream plane hit-channel

Hit pattern of PDC on each plane. A cable crosstalk? between L-Z2 and L-Z2D and systematic miss-connection for Z-normal-planes exist. It is unknown at which stage this cross talk happened, but systematic miss-connection is supposed to be generated at PDC flat cable output.

The cross talk has been fixed at the TKO backplane between MA=7 and 8 with SA=0~15 (P50M-13 and P50M-15) at 22th, Aug.

Even after this error has been fixed, only the profile for z-plane looks fine. This may be generated at the connection on PDC.

To be done on tracking....

1. BLC tracking: shift correction, time-to-time dt-dx reconstruction.

2. VDC tracking: time-to-time spline correction.

3. PDC tracking: shift correction, time-to-time dt-dx reconstruction.
