  // and the collections hold channels (e.g. up to 24 straws in the TRT endcaps).
  // Here we construct, for the whole detector, the ids of the collections (14912 TRT detector elements/modules)
  // and the number of channels (straws) in each collection according to the numbering scheme in the TRT RDO container.
  // A total 350848 straw ids can be defined using these two vectors since the id of each straw simply follows from the
  // previous id starting from the id of the collection that contains it.
