Description

Taking two geometry files as examples:

In Geometry for 08733:
Module /nustorm/data2/lib/MAUS-v2.7.0/geometry/08733/Tracker1.dat {
Position -3.13799656162 2.13409107222 19305.4695508 mm
Rotation -0.039823 0.05614642 0.0 degree
}
EndCoil1_1:
Position -1.4949 -1.1049 18644.45 mm

In Geometry for 08156, on the other hand,
Module /nustorm/data2/lib/MAUS-v2.7.0/geometry/08156/Tracker1.dat {
Position -2.91523621231 2.89763836084 19398.9681146 mm
Rotation 0.0710004400027 -0.0529999952483 0.0 degree
}
EndCoil1_1:
Position -1.4985 -8.2462 18656.03 mm

If you compare the relative position of TKD and TKU w.r.t. the abs., you will find that the recent geometry gives asymmetric TKU and TKD placement from center of abs.
Moving TKD while keeping ECE almost fixed is not physical and needs to be resolved right away. Re-recon should be done timely to allow analyses to continue.

Thanks.
