<comment> Models describe the overlapping of staves along phi, either (I) via offsets or (II) via distinct radii ("rmin1/2"). Solution (II) is only partially implemented: would require FOUR distinct "radius" in the readout segmentation. Note that in any case "rsensor" must be set equal the "radius" of the corresponding segmentation and is used internally to double-check the consistency between the stack of "module_component" and the segmentation "radius". </comment>
