WeÕre talking about thermal, collisional/coronal, equilibrium, optically thin plasmas hereÉprobably
Diagnostics and Physical Properties
Temperatures and overall emission levels: DEMs
Densities: line ratiosÉbut also source
location via f/i
Abundances: line ratios and
line-to-continuum ratios
Kinematics: line
broadening and profile shapes
Chandra (and XMM)
have increased the spectral resolution available to X-ray astronomers by almost a
factor of 100.
