One of the earliest full-spectral EIS observations of the quiet Sun, with the 1″ slit on 2006-12-23. From left to right and top to bottom: peak DN in the Fe XII 195.1 Å line; FWHM of the three main Fe XII lines, as a function of their peak intensities (DN); intensity ratios of the lines, as a function of the peak intensities of the strongest line. The dashed lines indicate the expected values.
