QUIET-SUN CONNECTION BETWEEN INTENSITY, DOPPLER-SHIFT, AND LINE BROADENING IN SOLAR ULTRAVIOLET EMISSION-LINES

The quiet-gun relations between the C IV line parameters, intensity, w avelength shift, and line broadening, are studied with high spatial an d spectral resolution. The material is ordered into equal intervals fo r one of the line parameters, and conditional probabilities are calcul ated. As the Doppler velocity increases, we find that redshifted profi les with a large intensity or line width constitute an increasing frac tion of the total number of profiles in a given velocity interval. For blueshifted profiles, on the other hand, the conditional probabilitie s for finding a profile with considerable intensity or line width decr ease as the line shift increases. Similar relations are found when the material is ordered according to intensity or line-width values.
