Detailed Description

The manager class for TOTEM RP geometry.

This is kind of "public relation class" for the tree structure of DetGeomDesc. It provides convenient interface to answer frequently asked questions about the geometry of TOTEM Roman Pots. These questions are of type:

• What is the geometry (shift, roatation, material, etc.) of detector with id xxx?
  
• If RP ID is xxx, which are the sensorss inside this pot?
  
• If hit position in local detector coordinate system is xxx, what is the hit position in global c.s.?
  etc. (see the comments in definition bellow)
