The FTD consists of a set of five silicon detectors placed
along both z-directions. The geometry is described in the CDR summary.
As for the VXD, the FTD hits are obtained by simple spatial smearing
of the energy deposits. They are contained in the array FTDHITS
in the routine GUTREV. As with all tracking detector
hits they are included in the common /CHGTRAK/ described below.
