Allowance of two plate base tracks displacement <50 um. Requesting base angle difference in two plate <0.02 . Requesting TT angular matching < 50 mrad in each projection . Selected tracks for manual scanning is 22, 44, 1, 22, 18 for each event. 5 tried and 3 found. Mark (*) is labeled for found event .

  9. Found event parameters (August comic ray events) event# CSD id X(cm) Y(cm) aX(rad) aY(rad) * 114927 11-14 3.3440 6.2335 0.0535 0.4590 * 160928 12-18 6.9993 7.9723 0.4666 0.5083 * 86199 12-16 9.1723 7.9175 -0.3940 0.5026 Found – prediction (pre correction -1.55cm,-0.55cm) event# CSD id dX(cm) dY(cm) daX(rad) daY(rad) * 114927 11-14 0.89 0.51 0.014 0.023 * 160928 12-18 -1.03 0.29 0.038 0.023 * 86199 12-16 0.56 0.13 0.013 0.027 Residuals is similar to Rock Muon events.

  11. Rock Muon October Run • event# Brick id# X(cm) Y(cm) Z (cm) aX(rad) aY(rad) • 1064775 370 181.539 -288.029 -401.821 -0.0839 0.0259 • (2.049 ,8.541 )  Film coordinate • Scanning Area is 5.05cm x 4.48cm • Requesting angular cut to TT 50mrad , 50mrad • 1 candidate send to manuacl check and it was confirmed as real . • event# Brick id# X(cm) Y(cm) aX(rad) aY(rad) • 1064775 370 1.4992 8.5825 -0.1005 0.0011 • dX(cm) dY(cm) daX(rad) daY(rad) • residual  (-0.550 0.0415) (-0.0166 -0.0248) • So the accuracy looks similar with August run result .

  12. Summary on CS scanning @Nagoya August run Rock muon events 4 found /8 tried Comic ray events 3 found/5 tried For Rock muon events : one not so edge part and 3 events Edge part (< 3mm) should be found For Cosmic ray events : remaining 2 events is center of film And try to enlarge angular tolerance to be Base Track Since angle is larger as 0.4 or 0.5 So shrinkage factor collection is important. October run Rock muon events 1 event (1 Brick) :: FOUND ! CS  Brick is not yet done , but soon .. Cosmic ray (4 min.) 3 Bricks Will be reported in CS Brick 8 cm X 7 cm scanning about 40 tracks found k
