As a result, the line shapes can vary according to spectrometer resolution, observation time, etc. Mainly because such effects can affect the measured wavelengths, we have given no more than three decimal places for the lines of Hg I. Using a low-pressure electrodeless lamp source, Sansonetti et al. [SSR96] have made high-accuracy measurements of 26 of the Hg I wavelengths measured by Burns et al. in the 2536-5791 Å region; the resulting standard deviation of 0.003 Å between the two sets of measurements may be at least partly due to line-shape effects. We also note that the wavelengths given here should not be used for calibrations based on lines from pencil-type lamps if uncertainties smaller than 0.01 Å are desired; measurements by Sansonetti et al. [SSR96] in the region 2536-5791 Å show the pencil-lamp Hg wavelengths to be systematically longer than the values of Burns et al. by an average of 0.0068(32) Å.
