Comparison of the column densities derived for comet Hale-Bopp on Dec. 19/20, 1997, by H05 and this work, computed with the same parameters. Black lines: column densities of C3 and C2 taken from H05. Dashed red lines: column densities computed by the model of this work. Blue lines: column densities of this work, scaled to match the profiles of H05. The dashed green lines show the Haser profiles of C2 and C3 according to Rauer et al. (2003).
