Source: Chiang (2023)
Chiang (2023) performed a reanalysis of the SFD (Schlegel, Finkbeiner & Davis 1998) reddening map, using correlations with large-scale structure traced by WISE galaxies to remove extragalactic contamination from the cosmic infrared background (CIB). The corrected reddening map and mask, plus the CIB map and error map, are available for download.
Version 2 (Aug 2023) - providing the LSS correction in a larger footprint outside the original mask, and adding a HEALPix NSIDE 2048 version of the original SFD map.
