The 3-D extinction law in the 2nd quadrant of the Galactic disk
Abstract
We estimate the 3D extinction law in the optical-NIR bands for a line of sight in the 2nd quadrant of the Galactic disk. Two dust lanes are identified at ~9 and ~10.25 kpc in both A V and R V , indicating that the size of the dust grains in the spiral arms is larger than that in the inter-arm regions.
