The tables include data concerning six He-like ions: wavelengths, transition probabilities, wavelengths at which the radiation temperatures should be determined. Line ratios (G and R, see definition in table 1 below) for six He-like ions from Tables 3 to 69 for various parameters: density (n_e_), temperature (T_e_), dilution factor (W), radiation temperature (T_rad_), and spectral resolution. Atomic data (appendix A) concerning the unresolved satellite lines are displayed (from Tables A1 to A6).
