Goals
Evaluate alignment precision as a function of available hits for each elements using MC.
Apply alignment on the BFEM data and find if it is consistent with the optical measurements.
Status
RootAnbalysis procedure is understood.
BFEM geometry is understood.
Straight line fits are performed. Bias hit and track rejection criteria is being developed.
Plan
Jan 2002: understand the geometry of the BFEM, straight line fits on TKR hits.
Feb 2002: plot residuals in each plane, develop codes to obtain x and y shift of each element.
Mar 2002: develop codes to obtain shift and rotations of each elements.
Apr 2002: develop codes to obtain alignment constant for all elements.
