AN ANALYSIS OF THE SHAPES OF ULTRAVIOLET EXTINCTION CURVES .3. AN ATLAS OF ULTRAVIOLET EXTINCTION CURVES

In this paper, we assemble the basic data needed to produce UV extinction curves for a sample of 78 stars which have been analyzed in previous papers of this series. The data include spectral types, visual photometry, parameters used to produce fits to the UV extinction curves, distances to the program stars, and line-of-sight H I column densities (most of which are newly determined from low-dispersion IUE data). We also include a detailed discussion of the observational and numerical techniques employed to obtain the results, so that the process can be reproduced easily. The UV extinction curves and their analytic fits are displayed graphically. In this way, the reader can easily assess how well the fits obtained by the curve parameterization scheme represent the data, and the quality of the observations used to derive the fits.
