Spitzer Source List

We have cross-matched the Spitzer Enhanced Imaging Products (SEIP) Source List with NED, integrating selected quantities including photometry in 5 IR bands:
  • 42,089,764 SSTSL2 sources from the SEIP cross-matched with NED, yielding:
    • 37.4 million new NED objects
    • 4.7 million cross-IDs to existing NED objects
  • 360.5 million photometric data points in the IRAC 3.6, 4.5, 5.8, 8.0 micron, and the MIPS 24 micron bands.
