| Abstract: |
We present simulations of the expected performance of the XMM Reflection Grating Spectrometer, the AXAF Low Energy Grating Spectrometer, and the XMM European Photon Imaging Camera. We discuss quality and limitations of diagnostics of temperatures, emission measures, emission measure distributions, velocity fields, and electron densities. Although the presented simulations are idealized, they nevertheless show that a number of physical phenomena in stellar coronae are within reach of the instrumental capabilities. |
