Abstract:
We 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.
Description:
We have considered how one should measure the distance and extinction
to individual stars for use in constructing extinction maps of the
whole Galaxy. We advocate the use of monochromatic extinctions, since,
unlike bandpass measures such as AV and E(B-V), monochromatic
extinctions are linear functions of the dust column density and are
independent of the source SED. In particular we suggest the use of
A4000, the monochromatic extinction at 4000Å because of its
insensitivity to the dust grain size distribution.
Files for converting from A_4000 to passband extinctions at 35
RV extinction law value and for 11 photometric systems.

Note (1): The tables provided here can be used to convert from A_4000, the
monochromatic extinction at 4000Å, to extinction in a range of
commonly used photometric bands following equation 11 of
Sale & Magorrian (2014MNRAS.445..256S 2014MNRAS.445..256S):
A_X = alpha_X A_4000 + beta_X A_40002.
