Query: Dust in three dimensions in the Galactic Plane   We present three dimensional maps in monochromatic extinction $A_{\rm 0}$ and
the extinction parameter $R_0$ within a few degrees of the Galactic plane.
These are inferred using photometry from the Pan-STARRS1 and Spitzer Glimpse
surveys of nearly $20$ million stars located in the region $l = 0-250^{\circ}$
and from $b = -4.5^{\circ}$ to $b=4.5^{\circ}$. Given the available stellar
number density, we use an angular resolution of $7' \times 7'$ and steps of
$1{\rm mag}$ in distance modulus. We simultaneously estimate distance modulus
and effective temperature $T_{\rm eff}$ alongside the other parameters for
stars individually using the method of \citet{Hanson2014} before combining
these estimates to a complete map. The full maps are available via the MNRAS
website.
