ABSTRACT
The calculated flux distribution in the 300 to 400 nm region only fits the
observed distribution closely for both the Sun and Arcturus when the complete
atlas9 line list is used. However, a good fit to the detailed shape of the
observed high resolution spectrum in the Sun may only be obtained by using a
sub­set of this line list that only includes lines with the highest quality atomic
