11. January 10, 2006207 th AAS Meeting, Washington, D.C. 11 Archive services contracted to the NASA/IPAC Infrared Science Archive (IRSA). Central archive contains all refined COSMOS data products: space- and ground-based; images, spectra, and catalogs. Both public and team-only archives. Data is moved to the public archive according to standard data policies. All data products are fully documented. The COSMOS Archive

12. January 10, 2006207 th AAS Meeting, Washington, D.C. 12 ATLAS Basic image-based graphical search service. Locate COSMOS data by interactively browsing the COSMOS field. Cutouts Service Extract selected data from precisely specified region(s) of the COSMOS field. Includes a table upload option for batch jobs. Direct Download Download FITS and other data files directly from the archive, using the COSMOS file naming convention to aid selection. GATOR Catalog query service. Locate and correlate objects in COSMOS catalogs with queries based on catalog contents (e.g., RA/DEC, radio flux, K magnitude). The COSMOS Archive http://irsa.ipac.caltech.edu/data/COSMOS/

13. January 10, 2006207 th AAS Meeting, Washington, D.C. 13 COSMOS is a large, ongoing survey, utilizing a significant number of ground- and space-based observatories. The refined data products are being released to the community on a regular schedule. We encourage everyone to learn about the project, visit the archive, and consider pursuing interesting projects of your own in the COSMOS field.
