Mean Galactic Extinction Curve
Abstract
The paper discusses the concept and application of mean galactic extinction law. The existing "mean curves" are usually averaged over limited samples of (nearby) objects. Anew method of averaging the curve by the Galaxy itself (ie. derived from the photometric and spectrophotometric data of very distant stars) is proposed. Such a curve may be compared to those observed in other galaxies or used for dereddening very distant stars. The analytical fit facilitates calculations of the extinction at any wavelength.
