Notes. The results are presented for each channel (CH) and phase state (δ). The values represent averages across the datasets used, with the uncertainties calculated as the standard deviation among the different datasets. The final row reports the mean values for each phase state, with uncertainties obtained by propagating the uncertainties in the mean calculation across channels, based on the expectation that the errors should be consistent across channels by design. We observe that the quoted uncertainties come from only three datasets tied to this specific instrument setup. Although this limits the statistical strength of the estimates, it reflects the available commissioning data and offers a useful indication of parameter stability. Future calibration campaigns will improve on this aspect.
