The focus is upon the energy resolution that is needed in order to disentangle the different spectral components. It is shown that there is an urgent need for high spectral resolution, and that a spectral resolution of 1 eV, if possible, leads to a significant increase in diagnostic power as compared to 2 eV resolution.","authors_text":"J.S.
