  1. Wave form of signal depends on the angle between the track and the pad plane. Angle dependence of residual in Z niiyama Wave form of signals which used to calculate the center of spatial coor of the cluster. lambda < 10 Layer 5 Lambda > 70 layer4 300 The wave form Is distorted for large Dip-angle tracks. This effect is seen for all layers.

  2. The algorithm of finding Z in a cluster. Center-of- gravity peak • Analyze in each pad • peak-time (a) • center-of-gravity in FWHM (b) • take average in pads by weight of • pulse height • sum up adc value of each pad for • every time bin ( projection) Center-of -gravity in FWHM time time Z calcurated In each pad Pad Id Sum up Adc of each pad for each time bin time Take mean of Z coor from each pad by weight of pulse height Pad Id

  3. resZ vs Lambda peak time (a)

  4. resZ vs lambda center-of-gravity in FWHM (b)

  5. resZ vs Lambda projection & peak

  6. resZ vs Lambda projection & take center-of-gravity in FWHM

  7. The dip-angle effect was not corrected. • We need to manage multi-peak in a pulse. time In each time bin calculate (x,y,z) coor. and track them by RK or circle fitting Pad Id
