Min  Max ($eV$) Sampling ($eV$) Resolution ($eV$) Position accuracy ($eV$) Absorption edge #1 16850.0  18000.0 0.874 $Y$ (K: 17.0384 $keV$)  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: Y metallic foil (first maximum of the derivative set at 17038 eV).
Definition: incidence and emergence angles are positive with origin at nadir. Emergence angle in transmission is larger than 90° (=180°i).
