The output of the first cycle (red path) is used as the input for the second cycle (green path). These branches are then combined (blue path) and profile scans taken at equivalent heights are used to calculate the MAE with Eq. (4). To find the contribution to the MAE caused by the instrument, the first cycle is repeated a statistically significant number of times, and an array of MAE values calculated by cross-comparing these. The fluctuation in the MAE is then caused by the system only, and set as the acceptance threshold.
