Min - Max ($eV$) Sampling ($eV$) Resolution ($eV$) Position accuracy ($eV$) Absorption edge #1 12550.0 - 13000.0 0.649 $Se$ (K: 12.6578 $keV$) - 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: Se metallic foil (mesh) (first maximum of the derivative set at 12658 eV). The resolution of the spectrometer analyser was 1.15 eV (FWHM of the elastic peak).
Definition: emergence angle is positive with origin at nadir. Azimuth origin (increasing clockwise) is arbitrary.
