OUTLINE

1.B off
Aligned scenario
Misaligned scenario in X:M4Aside=3mm, M4Cside=-6mm
2.B on
Aligned scenario
Misaligned scenario in X:M4Aside=3mm, M4Cside=-6mm
Three differents possibility for each of them (in order of analisys):
1.Ctalk (big pad);
2.No Ctalk;
3.First pad selected;
New geometry and the last version of Gauss, Boole, Brunel are used in all the scenarios . M1-M5 are the fixed stations.

But I think that rebbining for the chamber dimensions in the case of Y, we can use the Ctalk (big pad) without troubles
CONCLUSIONS
• I think that the best selection for us is to use the “PADONE” for several reasons:
- Shape of X (Y rebbining) residual distributions
- Number of tracks respect No Ctalk selection
