Diffuse Infrared Background Experiment (DIRBE)
It is an all-sky survey performed at the ~1°
resolution in 10 bands:
1.25 microns (Band 1),
2.2 microns (Band 2),
3.5 microns (Band 3),
4.9 microns (Band 4),
12 microns (Band 5),
25 microns (Band 6),
60 microns (Band 7),
100 microns (Band 8),
140 microns (Band 9)
and 240 microns (Band 10).
Flux convention: nu*I(nu) = constant
.
Maps are in unit of MJy/sr
.
Healpix maps have been generated from the sixpack
format.

DIRBE Zodi-Subtracted
The Zodi-subtracted maps were subtracted week by week and the residual intensity values were averaged to create the ZSMA Maps.
