0004 Two daughter boxes share the x=0 face exactly. The photon beam enters the
0005 left box, reaches the shared face at a steep angle, crosses the right box,
0006 and is detected by the nested sensor.
0007
0008 The short absorption length belongs only to the common parent. If the
0009 entering sibling is not selected, the beam is totally internally reflected.
0010 If the left sibling's carried material is not used for the segment ending at
0011 the shared face, almost all photons are incorrectly absorbed as parent
0012 material before reaching the sensor.
