Detailed Description

Prism class used for HF volumes. HF volumes are prisms with axes along the Z direction whose face shapes are set by

Required parameters for an ideal Z prism:

• eta, phi of axis
• Z location of front and back faces
• eta width and phi width of frontface

Total: 6 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 HALF-widths and the tower z thickness.
