Color-coded “unfolded” model spectra in the range 10–30 Å  computed for RGS1 and RGS2 for the fitted model of OBS3. The green, blue, purple, and red denote the normalized emission spectra of plasma components kT₁, kT₂, kT₃, and kT₄, each with the single values given in Table 4. The black line is the observed spectrum. The model from the RGS2 detector was used for all wavelengths except for the 20–24 Å  gap, and for this gap the RGS1 model was used. This accounts for small discontinuities in the emissions at these wavelengths for the kT₂ and kT₃ plasma components. The kT₃ and kT₄ emission are almost as well described by a broad DEM centered at a high energy.
