Figure 1754 shows an Al Kα (1.486 keV) EDS profile obtained with an old HpGe detector. This severe distortion of the peak shape and the large shift of the peak position due to extremely incomplete charge collection make the measurements at energies below ~2 keV (especially just above the energy of Ge L absorption edges from 1.2 to 1.4 keV) impossible.
