A jpsi and lmvm version of v21a much geometries with the centre of the magnet redefined as the global origin.
v21a geometries use the target position as its local origin therefore a translation of -40cm suffices.

This was generated by directly editing the tof_v20b TFile. In particular the top volume name and title was renamed. The transformation was rewritten from being 800 cm from the target to 760 cm from the centre of the magnet.

Generated from the edited TFiles of v18a and v18b. These were at the correct
location as they were shifted in CbmMagnet.cxx by 40cm. Only change
therefore was to update the volume name and title.

Centres the magnetic field at the global origin.

Includes PSD geometry.

Rewrites psd_v20b global origin as the centre of the magnet.

Created by direct modification of the TFile

Uses centre of magnet as global origin.

Reverting accidential deletion of file.

changes tag

Allows standard macros to use test geometries with global origin defined as the centre of the magnet.

Not tested but TRD placement is writtent relative to the centre of the magnet (3.7 m)
instead of previously relative to the target (4.1m).

Was generated from the trd_v20b_1e TFile

v17a_1e is shifted by 40cm upstream which is consistent with moving the global origin from the target to the centre of the magnet.

Generated from the macros supplied by Mehul

Root file from the edited TFile v18a which is the magnet with two installed clamps.

Setup file for testing is introduced.

Experimental target file with segmented layers.

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 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.
