"comment": "Volumes of the ALICE Run 3 geometry whose relation to the field is known independently of this tool, from the geometry of the LHC machine elements around the RB24 beam pipe. Pass this file to o2-sim-geometry-doctor --verify-anchors to check a run against them. The five copper tubes sit 14 to 63 cm clear of the machine band in z and must come out field-free; RB243 and RB243A are assemblies, so they carry no material and nothing can be flagged on them; caveRB24 must NOT come out field-free, because what its daughters leave over is a sliver of cave air between an oval beam pipe and a circular field cylinder that carries more than 13 kG; and RB24B1BellowM is placed in the solenoid fringe while carrying a field-free medium, which is what the reverse audit exists to find.",
