Absorption-edge scans in MxCuBE. (a) A scan is launched by clicking on an element in the periodic table in the ‘Energy scans’ tab. (b) Following a scan, the spectrum is analysed using CHOOCH (Evans & Pettifer, 2001 ▶), plots of f′ and f′′ against photon energy displayed and energies for the collection of peak, inflection point and remote wavelengths suggested. (c) Accepting the suggestions for the energies at which data are to be collected activates MAD/SAD data collection in the Collect tab. Here, the number and order of collection of datasets can be defined.
