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.
