VizieR Online Data Catalog: 3D extinction map of northern Galactic plane (Sale+, 2014)

We present a three dimensional map of extinction in the Northern Galactic Plane derived using photometry from the IPHAS survey. We construct the map using a method based on a hierarchical Bayesian model as previously described by Sale (2012MNRAS.427.2119S). In addition to mean extinction, we also measure differential extinction, which arises from the fractal nature of the ISM. The method applied also furnishes us with photometric estimates of the distance, extinction, effective temperature, surface gravity, and mass for ~38 million stars.

Further details about the data as well as additional formats and data products are available via http://www.iphas.org/extinction.
