v21f: STS geometry is similar to the version v21b. The target position considered from -4 cm.
The geometry can be used with the beampipe with diameter 40 mm upstream side and 104 mm downstream side.
The geometry has beampipe flange on the back-side of the wall.

v21g: STS geometry is similar to the version v21e. The target position is at -40 cm considering global origin
from the center of magnet. The STS local coordinate is from the last station.
The geometry can be used with the beampipe with diameter 40 mm upstream side and 104 mm downstream side.

In both geometry, the STS box and the beam pipe flange is made of Carbon fiber: The material has 70% carbon fiber with
density 1.75 g/cm3 and epoxy resin (30%) with density 1.2 g/cm3. The material is defined in media.geo file as
STS_CarbonFiber_21.

Change in tranformation from global origin (centre of magnet) to local origin of sts (last station) to a 59.5cm shift.
Front face of sts from a target placed at 44cm is now 1.6 cm.

The macro loops over the branches contained in the input file and reports
the sizes of the differnt branches. The output is a table written to cout.
The table is sorted from smallest to largest sizes.

Before the change it was necessary to define an environment variable to switch
between different test suites like for example the Experimental or Nightly
tests. Now the test suites are chosen by the CMake command line parameter
CBM_TEST_MODEL. These are Experimental, Nightly and Weekly which differ by the
number of executed tests.

v21a has stations with extended pitch, uses the old beam pipe, repositions the FEB boxes, and changes the material(Airex) for foam in sts wall.
v21b has stations with extended pitch, repositioned central ladders according to 40 mm diameter beam pipe and new material(Airex) for foam in STS wall. New nomenclature has been applied to halfladders from up(u) to top(t) and down(b) to bottom(b).
v21c has stations with extended pitch, repositioned central ladders according to 55 mm diameter beam pipe and new matrial(Airex) for foam in STS wall foam
v21d has stations with extended pitch, repositioned central ladders due to provision for a 40 mm diameter beam pipe. The back side wall has a honeycomb structure Airex matrial used
v21e has the centre of the magnet along the beam line as the global origin point. Additionally the local sts origin (x=0, y= 0, z= 0) is taken as the centre of the last sts station along the nominal beam axis. New Nomenclature has been applied to halfladders from up(u) to top(t) and down(d) to bottom(b).

The central ladders are moved upward (y-direction) due to the conical beam pipe with 40 mm diameter upstream side and 100 mm diameter in downstream side.
