- Mike reported on his plan for the FDC alignment (see the link above). On a scale of +/- 250 microns one certainly sees in the residuals some non-uniform features over the area of the chambers. The residuals are from a run with magnetic field and tracking through both CDC and FDC without excluding the corresponding chamber from the track. The plan is to use MILLEPED but before that it requires some work:

On a scale of +/- 250 microns one certainly sees in the FDC residuals some non-uniform features over the area of the chambers. The residuals are from a run with magnetic field and tracking through both CDC and FDC without excluding the corresponding chamber from the track. The plan is to use MILLEPED but before that it requires some good work: fix some issues with the output from the Kalman filter, calculate full co-variance matrix (not only diagonal elements), implement straight line tracking through both CDC and FDC, Standardize geometry and alignment constants.
  
- Mike made a presentation (linked) on his studies of the CDC/FDC transition region. He used straight tracks through the FDC and looked at the residuals w.r.t. the CDC wires. This is the procedure used by Lubomir to find the CDC offsets w.r.t. FDC except that Mike used the standard Simon's tracking. Mike showed there's ~20% more tracks in the 10-30 deg region after applying the offsets. These offsets will be included for the next analysis run.
