Opacities
Mean Opacities can be provided for hydrogen-rich, molecule dominated gases.

The means are based on a data collection from the Copenhagen SCAN data base and the HITRAN data base.
Mean opacities have been calcualed for
AGB stars (Helling et al. 2000),
planetary atmospheres (Frakis 2001),
protoplanetary disks (Semenov et al. 2003),
planetary and stellar evolution (Helling & Lucas 2009)
