Scientific paper

Surveys of abundances for species well suited to IUE's wavelength coverage and spectral resolution are undertaken to acquire interstellar line data for a large number of stars and column densities greater than those of previous instruments. A complex set of interactive computer programs has been developed for the efficient analysis of the IUE data, which is described along with results on Si II column densities toward two moderately reddened stars. Silicon depletions are inferred in the cases of the two stars, HD 42088 and HD 151804, and their H I column density determinations are used to estimate the total hydrogen column density.
