2D NICEST Extinction Maps

2D integrated dust extinction maps in the K band, computed using the NICEST algorithm. We also provide the configuration files used to produce the maps. These maps are provided at their native resolution, but were smoothed to match the projected 3D dust maps in the analysis in Zucker et al. 2021. When computing cloud masses AK = 0.15 mag was subtracted from the Pipe extinction map, to account for unassociated background extinction. We caution that for applications other than those discussed in the paper, some of the extinction far beyond the cloud (at the edges of the map) can go slightly negative. This is due to the fact that the dust "zero" point (defined using a low extinction region as close to the cloud as possible) only applies locally near the cloud.
