Abstract / Description:We present three-dimensional maps in monochromatic extinction A0 and the extinction parameter R0 within a few degrees of the Galactic plane. These are inferred using photometry from the Pan-STARRS1 and Spitzer GLIMPSE (Galactic Legacy Infrared Mid-Plane Survey Extraordinaire) surveys of nearly 20 million stars located in the region l = 0°-250° and from b = -4.5° to 4.5°. Given the available stellar number density, we use an angular resolution of 7 arcmin × 7 arcmin and steps of 1 mag in distance modulus. We simultaneously estimate distance modulus and effective temperature Teff alongside the other parameters for stars individually using the method of Hanson & Bailer-Jones before combining these estimates to a complete map. The full maps are available via the MNRAS website.
