Abstract
The paper presents a collection of 115 extinction curves derived from low dispersion IUE spectra. The spectra have been reduced with the use of techniques designed to reduce the effects of random noise and the influence of residual spectral features due to classification mismatch. The magnitudes of other instrumental and interpretational uncertainties are estimated. The extinction curves are presented with normalization to EB-V = 1 and the far ultraviolet portion (λ < 1700 Å) is also shown for E13-17 = 1. The atlas (on a microfiche) includes examples of extinction originating in the diffuse medium and several major nebulae and dense clouds.
