Extinction Law Survey Based on UV ANS Photometry
Abstract
The paper presents an extensive survey of interstellar extinction curves derived from the ANS photometric measurements of early type stars belonging to our Galaxy. This survey is more extensive and deeper than any other one, based on spectral data. The UV color excesses are determined with the aid of "artificial standards", a new technique proposed by the authors which allows the special check of Sp/L match of a target and the selected standard. The results indicate that extinction law changes from place to place.
