A control pulse is modeled as an exact value compared to exact energy gaps. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

highlighted = computed this step

Energy gaps are target data

The target gap is 6 while the neighbor gap is 4. The control model keeps those gaps distinct.

A pulse is compared to the gaps

A pulse value of 6 is compared against both displayed gaps before a response is shown.
