Min - Max ($eV$) Sampling ($eV$) Resolution ($eV$) Position accuracy ($eV$) Absorption edge #1 7550.0 - 8451.0 0.4 $Co$ (K: 7.7089 $keV$) - Comments
- The resolution in the above table is the resolution given by the monochromator. The energy was calibrated by measuring the absorption edge of a reference: Co metallic foil (first maximum of the derivative set at 7709 eV).
Definition: incidence and emergence angles are positive with origin at nadir. Emergence angle in transmission is larger than 90° (=180°-i).

- The resolution in the above table is the resolution given by the monochromator. The energy was calibrated by measuring the absorption edge of a reference: Co metallic foil (first maximum of the derivative set at 7709 eV). The resolution of the spectrometer analyser was 5.2 eV (FWHM of the elastic peak).
Definition: emergence angle is positive with origin at nadir. Azimuth origin (increasing clockwise) is arbitrary.
