Remarks on the analysis
Using only well reconstructed events : TkrNumTracks=1
Taking recontructed vertex variables : VtxX0, VtxY0, VtxXDir, VtxYDir
All parameters derived from runs at 0 degree : Mean is the value to put in the Monte Carlo
SPS Table Position - global values
Table position statistics : Mean
*Average Horizontal Offset (mm) : -2.4
*Average Vertical Offset (mm) : 7.8
SPS Table Angle - global values
Table Angle statistics : Mean
*Average Horizontal Angle Offset (deg) : 0.12
*Average Vertical Angle Offset (deg) : 0.31
