X 3 -X 1 -Offset (mm) (X 3 -X 1 ) / (Z 3 -Z 1 ) (Y 3 -Y 1 ) / (Z 3 -Z 1 ) Use theoretical positions. No alignment yet.

10. 02/27/2009Jianchun Wang10 Summary  There are significant improvements.  We took about half million good tracks. They are useful to develop alignment codes and produce some convincing plots to get our European colleagues committed.  There are still problems need to be solved. These problem are not vital to our VELO test. Reset router frequently ( solved on 02/25 test ). E chip drops off. Kill mask ( had a successful attempt ).  Dave and I had a half day testbeam with me remotely. It worked fine and we will continue from time to time.  We are pushing for an April VELO testbeam.
