- Generated π- tracks using particle gun: 1-11 degrees
- Tilted FDC by θx=-0.0275 degrees, θy=0.0265 degrees
- Modified HDGEOMETRY/DGeometry.cc to read gobal position and rotation angles for FDC from XML
- Reconstructed events with nominal geometry (no tilt in XML)(red) and modified geometry with tilt (dark blue)
- Position pulls:
- Momentum pulls:
- Kinematic fit of simulate ρ events generated with above FDC tilt
- Reconstruction using nominal geometry (no tilt)
- Reconstruction using XML for tilted geometry
