Agenda:
Notes:
- Pass7 - 0.5 mm data:: 60% of files done, about 45 files fail out of 10,0000
- We need a solution for the 1.5mm data, since we do not have the svt flags for this data.
- We could check the noise in the detector to determine to analyze the event or not.
- Norman -
- ECAL wrt SVT
- Show the Nathan analysis for old pass, which showed the y-offset of the ECAL.
- Repeated the analysis with pass7 files - get FEE skim, plot nSigma versus Y
- The answer is 42. It is symmetric. Looks like it is too correct now?
- You can see the 3rd row of crystals from the plot.
- ECAL is symmetric w.r.t y=0 in the SVT coordinate system!
- Current location is @IP, there is a pull request to get this to the face of the sensor (Miriam)
- Where's the beam?
- Moller kinematics from pass7
- Invariant mass is still a little high. (Used gaussian for fit) gets 0.0333 instead of 0.0328
- Vertex x,y is consistent with 0,0
- The z position is found at 0.61
- Px,Py are close to zero.
- Does the acceptance of the tracker/ECAL influence this analysis? Answer is not clear.
- Kyle -
- Needs a review of the readout code - some ECAL expert.
- Nathan - Next week.
