The lever arms of the different gates with regard to the quantum dots are evaluated. The lever arm of a gate on a quantum dot is the factor by which the chemical potential of the quantum dot is shifted when a potential is applied to the gate. For multiple gates, this results in a matrix that describes the different effects the gates have on the potential. (TODO: Last 2 sentences necessary?) The lever arms are evaluated using a gradient evaluation. (TODO: How does the gradient evaluator work, alternatively cut this)

Sensitivity is determined by measuring the transconductance $G = \frac{dI}{dV_p}$, where $V_p$ is the plunger gate voltage. High sensitivity corresponds to sharp peaks in transconductance, indicating a strong response to changes in the plunger gate voltage.

In the final step, the script evaluates the Coulomb oscillation by scanning the plunger gate and measuring the current through the SET (TODO: Maybe explain coulomb blockade). From the width of the peak, characteristics such as the temperature of the system can be obtained. The peak voltage is important for qubit preparation, while the height determines initialization and readout times. A linear model is used to compensate for lever arm effects, ensuring accurate characterization of the SET's behavior.
