Galactic Dust
Reddening and Extinction |
You can specify coordinate by selecting a position on the above all
sky map.
Computes the interstellar reddening for a line of sight and/or
region of the sky, returning the corresponding 100 um 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. Read more on the science background, technique and
cautionary notes

created by Schlegel, Finkbeiner & Davis (1998).
