Foreground: Dust Map at 94 GHz
HEALPix, nested, res 9 (Nside=512)
Original Data Source:
D. Finkbeiner, D. Schlegel
Finkbeiner, Davis & Schlegel (see 1999 reference below) developed models to predict submillimeter and microwave dust emission, based on fits to data from their earlier 100 micron and 100/240 micron maps (SFD98) and extension to COBE/FIRAS frequencies.
The dust map provided here was constructed using the data and interpolation software distributed by Schlegel & Finkbeiner via their Berkeley mirror website. Specifically, their routine predict_thermal was used to create a prediction for dust emission at 94 GHz using their 2-component model 8. The resultant map in in units of mK, antenna temperature. Note that the data are undersampled at the HEALPix Nside=512 pixelization provided here. Additional products are available from the source websites.
