Detailed Description

A 2D segment for the DT system for Phi projection. It's an intermediate data class between the normal DTSLRecSegment2D class and the DTRecSegment4D. The difference wrt DTSLRecSegment2D is that the segments it represents is build with the two phi SL. So this segment DOES not belong to the SL (as DTSLRecSegment2D), but to the chamber (via a DTRecSegment4D). A DTRecSegment4D has one of these objects, and so can access the full information of the two projections.
