1. mu-pair Ozaki san

2. Kibayashi san circle: muons which do not go through DSSD #3 red triangle: muons going through the DSSD #3 the IP resolution is worse phi~150 degrees for details see http://www.hp.phys.titech.ac.jp/atsuko/post/2004/0408

3. DSSD3 hybrid 7 residual dist. of cosmic ray muons w/o magnetic field after alignment DSSD #3 seems to be not aligned correctly.....

4. Cosmic ray muons without magnetic field ( by Kibayashi san)

5. Haba san pointed out that this may be due to mis- wirebonding correct connection wrong connection

6. Actually I found many combinations of clusters whose sizes are one and two with 1 strip separation. I applied strip address corrections on hybrid #7 The odd strip number is subtracted by 2. if( hybrid == 7 && ( rla % 2 ) == 1 ) rla -= 2;

7. cluster width cluster positions on hybrid before correction hybrid #7 Hadron C events (run# 64)

8. cluster width cluster positions on hybrid After correction! hybrid #7

9. Hybrid #3 for reference. quite similar plots!

10. before after the correction
