There is one limitation for these tables that must be realized by users and this limitation is so important that you will see it listed on all of the Web pages. These tables were calculated with atomic models and have no molecular species in the equation of state and no molecular cross sections in the opacity calculation. Users must provide their own tables below 12,000 o K if they wish to include these important molecular contributions. This Web page is set up to allow users to examine or download a maximum of one mixture at a time. Since this file can be over 1 megabyte in size, it was felt that this is the practical upper limit for file transfers at the present time.
Some mixtures are smaller.
Individual tables may be displayed and plotted and then downloaded. These options can be exercised from the next Web Page after the mixture is selected. Main Opacity Web Page.
