PLAT220 Type_2 Test Ueq(max)/Ueq(Min) range for non-H atoms in non-solvent
This test reports on a larger than usual U(eq) range for the specified element type in the non-solvent/anion part of the structure. Too high or too low Ueq's may be an indication for incorrectly identified atomic species (i.e. O versus N).
