- The baseline geometry (GeomA) is Hall-D Geometry V4.
- Configuration of chambers: U (0 degrees), V (+60 degrees), W (-60 degrees)
- No half-cell offset between neighboring wire planes.
- Alternate geometry GeomB
- Configuration of chambers: UU' (0 degrees), VV'(-60 degrees), WW'(+60 degrees)
- Half-cell offset between primed and unprimed chambers
- In both cases I studied 3 cm separation between wire planes (nominal geometry) and 2 cm separation.
- Single pion tracks (p=0.5,1.0,1.5,2.5 GeV/c) generated from the center of the target and analyzed with the standard reconstruction
- The Lorentz effect was turned on, but no other smearing was applied
- The Riemann Fit was used to fit segments and determine the sign for the correction for the Lorentz effect
- Full track reconstruction with standard (ALT1) least squares fitter
