1. June 7, 2010COSMOS Team Meeting, IfA, Hawaii 1 The COSMOS Archive: Eight Years of Data Patrick L. Shopbell (Caltech), Nick Scoville (Caltech), The COSMOS Collaboration, And the NASA/IPAC Infrared Science Archive (IRSA)

2. June 7, 2010COSMOS Team Meeting, IfA, Hawaii 2 Some 115 journal articles have been published by members of the COSMOS team, using COSMOS data products. This includes ~40 papers in the last year! Key Source: ApJ Supplement Series - COSMOS Special Issue ApJS 2007 172, 1-559 (Sep 2007) An increasing number of papers are being published by researchers outside of the COSMOS team, using combinations of COSMOS data and independent observations. This will continue to increase, with the HST MCT, Ultra-VISTA, etc. COSMOS has clearly moved beyond our project to a “standard” survey field. Press releases have included large-scale structure maps (Scoville et al.), 3-d dark matter maps from weak lensing (Massey et al.), large collections of gravitational lenses (Faure et al.), and an estimate of the growth rate of bars (Sheth et al.).

5. June 7, 2010COSMOS Team Meeting, IfA, Hawaii 5 COSMOS Data Products: the Future ACS 2.0 data now released –Includes CTE corrections devised by the weak lensing team –This is the final release of HST ACS data Possible improved ground-based infrared: H-, Y-, K- band Additional VLT spectroscopy Smaller pointed observations: Keck spectroscopy, etc. Funding for the archive is expected to sharply decrease in the near future. Although IRSA will maintain our archive far into the future, ingestion of new data products may be performed only on a limited basis.  If you have any data to release, let’s get it in the archive soon!

6. June 7, 2010COSMOS Team Meeting, IfA, Hawaii 6 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 verified and documented. The COSMOS Archive

7. June 7, 2010COSMOS Team Meeting, IfA, Hawaii 7 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, including complete catalogs, 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/
