Detailed Description

Oblique prism class used for HCAL (HB, HE, HO) volumes.

Required parameters for an ideal oblique prism:

• eta, phi of axis
• radial distance (along axis) to front and back faces
• single bit - faces parallel or perpendicular to z-axis
• eta width and phi width of faces (same for front/back)

Total: 6+1 parameters

Internally, the "point of reference" is the center (eta/phi) of the front face of the prism. Therefore, the only internally stored parameters are eta and phi widths, the axis tower thickness, and the parallel/perpendicular setting. The parallel/perpendicular setting is encoded in the sign of the thickness. (positive = parallel to z-axis, negative = perpendicular)
