UUID: :ref:`8873AB20-35E0-4F13-A7DC-4C3E544A46AF <uuid-8873ab20-35e0-4f13-a7dc-4c3e544a46af>`

**Required Behavior:** The required relationship is a wavelength value associated with each effective detector position, represented generally as ``lambda(p) = f(p)``.

**Open Requirement:** Not In Docs: function form, polynomial order, coefficient format, extrapolation, uncertainty, and residual acceptance threshold.
