Almost all definitions are now in the definitions.xml Can you check and point what else to be changed?

[chchatte92]

The only concern I have is the

</documentation>
<sphere
  centerz="138.4*cm - DRICH_zmin"
  centerx="183.4*cm"
  radius="110.0*cm"
  />
<sphericalpatch
  phiw="30*degree"
  rmin="111.0*cm"
  rmax="179.0*cm"
  zmin="DRICH_snout_length + 3.0*cm"
  />

Can spherical patch rmax still be 179 cm given the ramx2 is 180 cm?

[c-dilks]

The z-positioning and length are difficult to change, since several other detectors depend on these parameters. I will push a commit that tries to do a bit better, but we're gonna need some help from other subsystem experts on this one...
