0004 /** \class DTChamberRecSegment2D
0005  *
0006  * A 2D segment for the DT system for Phi projection.
0007  * It's an intermediate data class between the normal DTSLRecSegment2D class and
0008  * the DTRecSegment4D. The difference wrt DTSLRecSegment2D is that the segments it
0009  * represents is build with the two phi SL. So this segment DOES not belong to
0010  * the SL (as DTSLRecSegment2D), but to the chamber (via a DTRecSegment4D).
0011  * A DTRecSegment4D has one of these objects, and so can access the full
0012  * information of the two projections.
