Galactic Dust
Reddening and Extinction |
You can specify coordinates by selecting a position on the above
all-sky map, a MONTAGE-generated mosaic of the individual
IRAS 100 micron images created by Schlegel et al.
This service gives the Galactic dust reddening for a line of sight,
returning a reddening map, the corresponding 100 micron intensity,
and dust temperature, along with statistics for each. The total Galactic
visual extinction is estimated and, in Single Location mode, extinctions
at multiple wavelengths are estimated. The reddening estimates are
from Schlegel, Finkbeiner & Davis (1998), who combined results
of IRAS and COBE/DIRBE. Read more on the science background,
technique and cautionary notes here:

NEW (July 2013): Newer estimates of Galactic dust extinction
from Schlafly and Finkbeiner (2011) are now provided
alongside those of Schlegel, Finkbeiner & Davis.
