v4.0 - Monolayer design with dead regions (experimental)

This version is an improved design of v2.0 as a result of the SciFiHarmonisation Workshop.

It has a stepwise beamhole (before: circular) and comes in three different versions:

FTv40:

• no 'triangles', i.e. horizontal border between top and bottom fibermat
• no 'sawtooth', i.e. the top and bottom modules are cut at the same y-value

FTv41

• no 'triangles', with 'sawtooth'

FTv42

• with 'triangles', with 'sawtooth'

All versions are available in the DDDB since release dddb-20141016.

In FTv4 the modules are concerned by the "StereoIssue", which means that X modules and U,V modules have different dimensions.

FTv4 will be superseded by FTv5.
