Figure 2
Illustration of the imperfect nature of a single-point energy calibration to correct for an angular offset in a typical monochromator. The top panel shows two spectra that have been corrected in energy to the Eedge, one of a perfect calibrated monochromator and the other from a monochromator with a 0.0233° angular offset. The middle panel highlights the energy offset that develops when the correction is based on a simple linear realignment of the edge position. The bottom panel shows the magnitude of this offset over the scan range. |
