ORFEOv6r3
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.
