Diagnostics of κ and temperature from Fe XVII from the MaGIXS spectra. Ratios of line intensities (in photon units) are indicated, with wavelengths of the lines involved listed together with the main self-blends. Individual colors denote the distribution, with black for Maxwellian, and blue, green, orange, and red for κ-distribution with κ = 10, 5, 3, and 2, respectively. Full lines correspond to spectra with for N_e = 10⁹ cm⁻³, while the dot-dashed lines correspond to N_e = 10¹¹ cm⁻³. Black long-dashed lines (available only for the Maxwellian distribution) show the effects of the recombination and ionization to and from the upper excited levels, together with cascades. See Sect. 3.3 for more details.
