192 Å blend, the most complex blend under consideration in this EIS raster. Shown here is the de-blended line, fitted using four Gaussian components, which are the coloured lines. The original spectrum is shown here as the histogram with error bars. The orange line is the Fe xi 192.627 Å line, green is Fe xi 192.814 Å, and the purple and blue lines represent the O v lines. The thin, dark blue line shows the overall contribution from the O v lines, and the solid black line is the total fit to the spectrum. The log scale on the y-axis enhances the weaker lines relative to the stronger lines.
