##   Information about trd.v13 geometries
#

# updated 2013-11-05 - by DE

# introduced new geometry naming scheme in Nov 2013,
  names are now easier to associate to setups:

- trd_v13p_1e.geo.root
- trd_v13p_1h.geo.root
- trd_v13p_1m.geo.root
- trd_v13p_3e.geo.root
- trd_v13p_3m.geo.root

The default macro is Create_TRD_Geometry_v13p_3e.C
all 4 other setups are generated in shell scripts by patching:

create_TRD_Geometry_v13p_1e.sh
create_TRD_Geometry_v13p_1h.sh
create_TRD_Geometry_v13p_1m.sh
create_TRD_Geometry_v13p_3m.sh


# introduced new geometry naming scheme in May/June 2013, 
  new geometries according to official z positions by Walter (v1.00):

- v13g - SIS 300, 10 layers, behind RICH, (z = 4100 mm), compact layers (dz = 450 mm)
- v13h - SIS 100,  4 layers, behind  STS, (z = 2600 mm)
- v13i - SIS 100,  2 layers, behind RICH, (z = 4100 mm), compact layers (dz = 450 mm)
- v13j - SIS 100,  3 layers, behind RICH, (z = 4100 mm), compact layers (dz = 450 mm)
- v13k - SIS 100,  4 layers, behind RICH, (z = 4100 mm), compact layers (dz = 450 mm)
- v13l - SIS 100,  4 layers, behind MUCH, (z = 4600 mm), compact layers (dz = 450 mm)
- v13m - SIS 300, 10 layers, behind MUCH, (z = 5500 mm), compact layers (dz = 450 mm)
- v13n - SIS 300, 10 layers, behind RICH, (z = 4600 mm), TRD streched in z, compact layers (dz = 450 mm)


# created new official ROOT TRD geometries (21.03.2013)

- v13c - as v13i, compressed, without 25 cm gaps between stations, z = 4.5m to 9.5m
- v13d - as v13s - 2 layers, SIS100
- v13e - as v13r - 3 layers, SIS100
- v13f - as v13t - 4 layers, SIS100
