cds-question@unistra.frextinctionphotometryWe present a method for obtaining the likelihood function of distance and extinction to a star given its photometry. The other properties of the star (its mass, age, metallicity and so on) are marginalized assuming a simple Galaxy model. We demonstrate that the resulting marginalized likelihood function can be described faithfully and compactly using a Gaussian mixture model. For dust mapping applications we strongly advocate using monochromatic over bandpass extinctions, and provide tables for converting from the former to the latter for different stellar types.2015MNRAS.448.1738Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/448/1738CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/448/1738https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/448/1738http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/448/1738https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/448/1738https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/448/1738http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/448/1738GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/MNRAS/448/1738/listList of files with conversion factorsrecnoRecord number assigned by the VizieR team.
