CDC Geometries

This table copies from "November 17, 2008 Tracking CDC/FDC" but with geometries H and I added

These represent the axial/stereo configurations that will be studied via simulation. The orientation is listed from outermost layer (top) to innermost layer (bottom).

Relative φ-shifts between layers is implemented in all designs. Note however that the shifts are not prime-fractions of the single cell shift that was originally used. Many of the numbers were locked in from other geometries but still provide a similar disruption of the layer alignments.
