Removing exactly the reached descriptor factors from positive energy

  1. theorem OAI.Falconer.descriptorProduct_mul_norm_le line 13
  2. theorem OAI.Falconer.independentAngularEnergy_descriptorProduct_remove line 27

    Source documentation

    The spatially constant factors are removed only after squaring and integrating. Every descriptor with an anchor deeper than the child remains.
