SBCA Bragg angle calibration with HERFD-XANES scans performed at different SBCA pitch values. (a) Selected alignment scans, performed on a dilute CuO sample, for SBCAs with i = +1 at different pitch values are compared with the HERFD-XANES measured for the i = 0 crystal. The pitch values are indicated as deviations from the values corresponding to the maximum of the elastic peak. (b) The sum of squared residuals, χ2 value, between HERFD-XANES data recorded for SBCAs with i = ±1, ±2 and the SBCA with i = 0 as a function of SBCA pitch-angle deviation. The dashed lines are second-order polynomial fits to the data.
