Verbose = 0 (default: PV_name + copy_number)

World

  "Calorimeter", copy no. 0

    "Layer", copy no. -1 (10 replicas)

      "Absorber", copy no. 0

        "Gap", copy no. 0

Verbose = 1 (PV_name + copy_number + LV_name)

"World", copy no. 0, belongs to logical volume "World"

  "Calorimeter", copy no. 0, belongs to logical volume "Calorimeter"

    "Layer", copy no. -1, belongs to logical volume "Layer" (10 replicas)

      "Absorber", copy no. 0, belongs to logical volume "Absorber"

      "Gap", copy no. 0, belongs to logical volume "Gap"

Verbose = 2 (PV_name + copy_number + LV_name + solid_name + solid_type)

"World", copy no. 0, belongs to logical volume "World" and is composed of solid "World" of type "G4Box"

  "Calorimeter", copy no. 0, belongs to logical volume "Calorimeter" and is composed of solid "Calorimeter" of type "G4Box"

    "Layer", copy no. -1, belongs to logical volume "Layer" and is composed of solid "Layer" of type "G4Box" (10 replicas)

      "Absorber", copy no. 0, belongs to logical volume "Absorber" and is composed of solid "Absorber" of type "G4Box"

      "Gap", copy no. 0, belongs to logical volume "Gap" and is composed of solid "Gap" of type "G4Box"
