0011  theXChannelBoundaries positions are the x low limits for each channel (EM section)
0012  theZLUMChannelBoundaries are the z low limits for each channel (LUM section)
0013  theZHadChannelBoundaries are the z low limits for each HAD channel at y = 0 position
0014  this coordinates are given with respect to the center of the enclosing volume (ZDC)

0016  tiltangle is the angle of the HAD section
0017  YLUM is the Y position of LUM
0018  dYPlate  is half height (DY/2) of the HAD and LUM sections
0019  dYLum is the half height (DY/2) of the LUM section
0020  dXPlate is the half width (DX/2) of all sections
0021  all dimmensions are in mm and rads
