Galactic Dust Reddening and Extinction


An All Sky view of the IRAS 100 micron imaging data, representing a MONTAGE-generated combination of the individual images created by Schlegel, Finkbeiner & Davis (1998).

DUST Software Tool Operational

Computes the interstellar reddening for a line of sight and/or region of the sky, returning the corresponding 100 micron intensity, reddening maps, region statistics and estimated Galactic extinction. The reddening is derived using the data and technique that Schlegel, Finkbeiner & Davis (1998) pioneered combining the strengths of IRAS and COBE/DIRBE. The user should beware that the technique is restricted by both spatial resolution limitations and assumptions that are used to derive the dust temperature along the line of sight.
