Table 2. Results of fits of asymmetry angles α and channel gaps D to experimental data.
The offset changes Δh are calculated in the energy ranges given using the fit parameters for the non-dispersive setup. ‘Cut’ refers to the design parameters, αp to the realized values (see Section 4) and αXAS to the results of the XANES measurements.
