Comparison of the modeled spectra of the Sun (left) and Arcturus (right). Each panel contains two graphics. In the main (upper) panel, the black line indicates the observed spectrum. The red and blue lines show the modeled spectrum using the original and improved line list, respectively. For the sake of clarity, these two lines have been offset by −0.10 and −0.05 in the y-axis. In the complementary (lower) panel, the residuals (data – model) using both line lists are shown. Finally, the profiles for the DIBs that motivated the corrections presented here and a putative cloud at v = 0 km s^-1 are included for reference.
