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

2 2 The algorithm of finding Z in a cluster. 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) peak Center-of- gravity Center-of -gravity in FWHM time Pad Id time Z calcurated In each pad Take mean of Z coor from each pad by weight of pulse height Pad Id time Sum up Adc of each pad for each time bin

3 3 resZ vs Lambda peak time (a)

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

5 5 resZ vs Lambda projection & peak

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

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