PROMISE column density mapping survey

One major part of the PROMISE program is a Galactic plane mapping project, the 'PROMISE survey'. The PROMISE survey produces 2" resolution column density data for thousands of molecular clouds and clumps in the Galactic plane. The survey is based on a combination of mid-infrared extinction, far-infrared dust emission, and near-infrared extinction data. The survey and data will be described in Kainulainen et al. (in prep).

Below, a sneak preview to some of the PROMISE data products is provided.

Instructions: Set the coordinate system from J2000 to Gal (drop-box in the top left corner). Then, search for the location 0 0 (using the looking glass button in the top left corner). The survey data should appear; use the mouse wheel to scroll in and out. You may need to wait for a while for the high-resolution data to load.

+ A first look to the dust column density data in the Galactic quadrant one: link. The map combines mid-infrared and HiGal column density data.

+ A first look to the dust column density data in the Galactic quadrant one: link. The map uses mid-infrared data alone.

+ Point-source subtracted Spitzer 8 micron data: link. Provides a view to the extended features in the Galactic plane without compact sources such as stars.
