The full-sky SFD98 E(B-V) map distributed here is in J2000 Equatorial coordinates with NSIDE=512. It was derived from the full-sky SFD98 E(B-V) map in Galactic coordinates that is available from NASA's LAMBDA portal [[https://lambda.gsfc.nasa.gov/product/foreground/fg_ebv_map.cfm | here]]. The LAMBDA full-sky Galactic Healpix map was drizzled onto J2000 Equatorial WCS FITS templates (each with 500 x 500 1.'5 square pixels), which were then combined using the drizzling algorithm to create the full-sky J2000 Equatorial Healpix map. More information about the limitations and caveats of the original Galactic SFD98 E(B-V) Healpix map is available on the LAMBDA page. \\ | The full-sky SFD98 E(B-V) map distributed here is in J2000 Equatorial coordinates with NSIDE=512.
