ORFEOv6r3
10. GeV muons
This data MC comparison was made with the last version of ORFEO.Here a new version of the smearing tool is implemented, this is based on the position smearing in the 3 directions: X,Y,Z of the 2 end points of the microtrack. In such a way the basetrack smearing of the slopes is obtained for free. In addiction, with this technique, the smearing ellipse in the Tx:Ty plane has main axes in the longitudinal and transversal direction, as seen in the data.

• The events were generated with OpRoot
• The smearing parameters are: Sx=0.4 micron, Sy=0.25 micron, Sz=2.5 micron. (these value were obtained with a tooning on the data)
