Quiet-Sun Connection between Intensity, Doppler Shift, and Line Broadening in Solar Ultraviolet Emission Lines
FREEN. Brynildsen1, O. Kjeldseth-Moe1 and P. Maltby1
Show affiliationsThe quiet-Sun relations between the C IV line parameters, intensity, wavelength shift, and line broadening, are studied with high spatial and spectral resolution. The material is ordered into equal intervals for one of the line parameters, and conditional probabilities are calculated. As the Doppler velocity increases, we find that redshifted profiles with a large intensity or line width constitute an increasing fraction of the total number of profiles in a given velocity interval. For blueshifted profiles, on the other hand, the conditional probabilities for finding a profile with considerable intensity or line width decrease as the line shift increases. Similar relations are found when the material is ordered according to intensity or line-width values.
