Zodi-Subtracted Mission Average (ZSMA) Maps
The ZL intensities recorded in the DSZA were subtracted week by week and the residual intensity values were averaged to create the ZSMA Maps, which give the best available picture of the Galactic and extragalactic diffuse infrared emission on degree or coarser angular scales. In many applications, the ZSMA Maps will supersede the Annual Average Sky Maps. Like the Annual Average Maps, the ZSMA Maps are provided in ten FITS binary tables, one each at 1.25, 2.2, 3.5, 4.9, 12, 25, 60, 100, 140 and 240 microns. Each row of the FITS table corresponds to a DIRBE pixel. One zodiacal light-subtracted intensity value, representing an average over the cryogenic mission, is given per pixel. The ZSMA files are on line.
