Atlas of Interstellar Extinction Curves of OB Stars Covering the Whole Available Wavelength Range
Abstract
The paper presents a collection of 436 extinction curves covering the whole available range of wavelengths from satellite UV to near-IR. The data were taken from the ANS photometric catalogue and from the compilations of IR photometric measurements. The data curves have been obtained with the aid of ``artificial standards": Papaj et al. (1993) and Wegner (1994, 1995). The visual magnitudes and spectral classifications of O and B type stars with EB-V>= 0.05 were taken from the SIMBAD database. The curves are given in the form of plots and tables E{lambda - V} / EB-V versus 1/λ. The observed variety of extinction laws among slightly reddened stars is apparently due to the various physical parameters of interstellar clouds.
