Opacity

   Instruction This database consists of two subdatabases. One provides mean and frequency -dependent opacity for single element in the fixed ranges of temperature and density, which is produced by calculation. Another one gives those results for mixture for specified temperature and density. Here the mixing of at most 20 kinds of elements is permitted and the results are produced by interpolation basing on the data of the first subdatabase. The ordinary user could retrieve the data for the elements which atomic number (Z) is less than 31. Only advanced user, who need registration, can search for the data with Z>=31.
