J/A+AS/105/77 Atomic data for O VIII and Fe XVII (Cornille+ 1994)
================================================================================
Atomic data and spectral line intensities for O VIII and Fe XVII
resonance lines as well as their O VII and Fe XVI satellite lines

Abstract:
The atomic data required to analyse low density coronal plasmas have been
calculated and used to interpret X-ray spectra observed by the Flat Crystal
Spectrometer of the SMM/NASA satellite in the 14-19 A wavelength range. The
emission lines correspond mainly to Fe XVI, Fe XVII, Fe XVIII and some ones
to O VII, O VIII.
