7 // for sensitive alignable volumes:
8 // 1) the look-up table mapping unique volume ids to TGeoPNEntries
9 // this allows to access directly by means of the unique index
10 // the associated symbolic name and original global matrix
11 // in addition to the functionality of the physical node
12 // associated to a given alignable volume
13 // 2) the look-up table of the alignment objects associated to the
14 // indexed alignable volumes
