Quiet Sun SYNOP1 observations on 2007-06-09 at 06:12 UT. Top row: peak DN along the slit, from the 90 s exposures. Second row: line widths (FWHM) from the 30 and 90 s exposures. Note the larger scatter in the 30 s exposures, for low DN, below 200. Dashed lines: instrumental FWHM as in the EIS software. Third row: ratios of total counts in the 192 and 195 Å lines, as obtained by summing the pixel values and the Gaussian fit; 192/195 Å and 192/193 Å line intensity ratios from the 90 s exposures (in photons, dashed lines indicates expected values); Last row: effective FWHM in the three Fe XII lines, and the ratio of the 195 versus the 192 Å widths.
