\caption{Comparison between various model runs for neutral anthracene 
(C$_{14}$H$_{10}$), using either the experimental 
\citep[$\sigma_{\rm lab}$,][]{job92a,job92b} or the theoretical 
\citep[$\sigma_{\rm th}$,][]{mal04} photo-absorption spectrum, in different RFs. 
Bands which are electric-dipole forbidden are enclosed in square brackets in 
the first column. In each of the other columns, we list the absolute flux 
emitted by one molecule in a given band and RF and, in parentheses, the flux
fraction in that band. Bands whose calculated flux fraction in the 
ISRF is less than 0.05\% are omitted.
