A column index can be created in order to speed access to the data in the column. For example, molecular weight might be an important column used in most searches of a mass spectroscopy database. If every row of the table has to be examined to determine if the value is between, say, 100 and 200, this would be slower than searching only those rows known to contain these values. One technique used to index columns of numerical data is to presort the values into a relatively small number of bins. The index records which rows belong to which bin. When searching for values between 100 and 200, only rows that belong to the appropriate bin need to be examined. 

The HITRAN Molecular Spectroscopy Database (References 1 and 2) is a compilation of wavenumbers and intensities of more than 1.7 million spectral lines of atmospheric constituents. It is a valuable resource for calculating transmission of the atmosphere, radiative energy transfer, and other phenomena. The graph below, which was supplied by Walter J. Lafferty (Reference 3), gives the...
