There are four sts beampipe can be used with different sts_version as described below

v21a: Old beampipe, can only be used with sts geometry version: sts_v21[a].

v21b: New beampipe. It has 40mm diameter upstream side and 104mm diameter (including cylindrical part) downstream side.
This beampipe can be used with the sts geometry version: sts_v21[b, d, f, h].

v21c: New beampipe. It has 55mm diameter upstream side and 104mm diameter(including cylindrical part) downstream side.
This beampipe can be used with the sts geometry version: sts_v21[c].

v21d: New beampipe. It has 40mm diameter upstream side and 104 diameter(including cylindrical part) downstream side.
This beampipe can be used with the sts geometry having a target position at -44 cm. which means it can only be used with the
sts geometry vesrion: sts_v21[e, g, i].

magnet_v21a is the shifted verison of v20a
magnet_v21b is the shifted verison of v20b
rich_v21a is the shifted verison of v17a_1e

Shifted by 40cm consistent with the change of coordinates from
old target position to centre of the magnet.

Having seperate translation for pipe_v16c causes problems for inclusion
of MVD. Translation via node shift instead.

As created by their respecitive macros.

STS v21h: The geometry has the target positioned at -4 cm. It can be used with the beampipe 40mm diameter upstream side
          and 104mm diameter downstream side. It has a beampipe flange on the back-side of the STS wall.

          In addition, the geometry has a sensor thickness 320 um which is similar thickness of the real silicon sensors purchased from the Hamamatsu Photonics
          for the use in the real experiment.

          Furthermore,the mico-cable is defined as a single volume attached to the silicon sensors. Micro-cable thickness (320 um) is choosen and
          the material Manganese is taken based on the calculation done based on the current microcable design, thickness and its material.
          The material is defined as STS_Manganese in the media.geo file.

STS v21i: The geometry has the target positioned at -44 cm from the center of the magnet. It can be used with the beampipe 40mm diameter upstream side
          and 104mm diameter downstream side. It doesn't have a beam-pipe flange on the back-side of the wall.

          In addition, the geometry has a sensor thickness 320 um which is similar thickness of the real silicon sensors purchased from the Hamamatsu >
          for the use in the real experiment.

          Furthermore,the mico-cable is defined as a single volume attached to the silicon sensors. Micro-cable thickness (320 um) is choosen and
          the material Manganese is taken based on the calculation done based on the current microcable design, thickness and its material.
          The material is defined as STS_Manganese in the media.geo file.

updated binaries files and media.geo file with a material name STS_Cable_21

Transformation between local sts origin (last station) and global origin (center of magnet) is now 59.5. Front face of sts to intended position of target (-44cm) is now 1.6 cm.

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 -44 cm considering global origin
from the center of magnet. The STS local coordinate is from the last station.

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.

Following https://redmine.cbm.gsi.de/issues/2119 and SWM discussion, recommended MVD version "v20c_tr" was not compatiable with sts "v19a".
This change should be reverted once a new STS geometry is available.

Fix the stage for the rebase check.
After the upgrade it lloks like that the pipeline doesn't run any longer in
the context of the forked project but in context of the master project such
that the project path wasn't correct any longer. This allows now to compare
upstream/master to HEAD.

v20a places PSD at position 10.5m and 12.95cm in z and x displacement with 0.0132 rotation round the y-axis which is consistent with a compact electron setup with a 1.1m BFTC at 12 AGeV/c

v20b places PSD at postion 11.1m and 13.75cm in z and x displacement with 0.0132 radians rotation round the y-axis which is consistent with a compact muon setup including its 5th absorber with a beam at 12 AGeV/c and a BFTC of 1.1m.
