Abstract
An algorithm, MEAD, is presented, which can map extinction in three dimensions, with fine distance and angular resolutions. MEAD is then employed when studying the structure of the outer Galaxy. We show that the Galaxy’s radial density profile takes the form of a broken exponential, with density dropping off more steeply beyond a Galacto-centric radius of ∼13 kpc.
