The Extended Source Catalog allsky images are presented in XSC Allsky. The PSC allsky image is showcased in the 2MASS image gallery. In order to directly compare the PSC with the XSC allsky images, we have transformed the PSC allsky images into the equatorial system used for galaxies.
2MASS Local Universe
Note: Known Milky Way sources (e.g., HII regions) have been removed from the XSC ALLSKY image, and thus the remaining XSC image is nearly 100% extragalactic in nature. Galactic (Milky Way) sources are primarily confined to the Plane of the Galaxy, as is easily seen in the XSC vs. PSC movie shown below.
As demonstrated below, the XSC is completely decoupled (for |glat| > 3 degrees) from the PSC since it is dominated by galaxies. Note the very red sources spanning the Galactic plane (|glat| < 3 deg) -- these are predominantly Milky Way in origin (and have been removed from the combined XSC+PSC allsky image, shown above).
