The background was model as a power law using a window of 10 eV width. The spectrum was deconvoluted by the Fourier-ratio method using low-loss spectra collected from the same region and under similar conditions except for a reduced illumination intensity. Analyst: P. Potapov. Temperature: Room. BEAM/Crystal: close to [101] zone axis.
