Light from Dark Clouds
Published online by Cambridge University Press: 08 February 2017
Extract
The purpose of the present investigation was to find out how far the existing photographic sky surveys can be used to derive physical parameters of dark clouds, without the need of new observations. In a recent paper a method of distance determination and extinction mapping of dark clouds by automated star counts on microphotometric raster scans of the ESO/SRC Southern Sky Survey (Stüwe, 1989, hereafter Paper I) is presented. The present paper does a second step, which is based on the fact that dark clouds are marked by an intrinsic surface brightness (Barnard, 1927).
