Table 2. Summary of recording parameters for one XAS spectrum by FF imaging and by standard quick-EXAFS for the three case studies.

The number of points per spectrum for standard quick-EXAFS corresponds to the raw number of energy points collected by the PANDABOX hardware interfaced with the monochromator encoder position and providing the trigger line to the 16-bit analog-to-digital converter for synchronously accounting for the ionization chamber currents (Briois et al., 2016 ▸). Interpolation of the oversampled (energies, intensities) values is then performed over an energy grid with a regularly spaced step of 0.25 eV in the XANES range and 2.0 eV in the EXAFS range leading to 1000 to 1500 energy points in each spectrum, depending on the case study. The time resolution for standard quick-EXAFS is equal to the time per spectrum insofar as spectra are acquired in both ascending and descending Bragg angle scanning contrarily to FF imaging for which only image acquisition is performed for ascending Bragg angles.
