IRSA - Infrared Science Archive

IRSA's Data Collection Explorer (DCE) includes several new spectroscopic data sets. https://irsa.ipac.caltech.edu/irsaviewer/dce

The AllWISE Full-Depth Ecliptic Polar Atlas is now available at IRSA. https://irsa.ipac.caltech.edu/data/WISE/FDEPA/overview.html

The Red MSX Source Catalog is now available at IRSA. https://irsa.ipac.caltech.edu/data/RedMSX/overview.html

Here's a vivid demonstration of how the new hierarchical catalog features work. The first image is of a certain portion of the sky with a catalog overlaid in the old version. There's no visual indication that the entire catalog isn't, in fact, overlaid on the image. The second image is what happens now in the tool -- same catalog, same region of the sky. The entire catalog now really is overlaid; you have to zoom in close enough that there are 'few enough' sources in the field of view, and then it will show you all the sources. When you zoom out, it will show binned tesselations on the sky with an indication of how many sources are in that cell. You can control the cell size and how these cells are represented -- see the online help!

*We have updated IRSA Viewer (& DCE, the Catalog Search Tool, the Data Discovery Tool, and IRTF), Finder Chart, WISE, and ZTF.
*Catalogs are now shown hierarchically. It will show symbols with a number indicating the number of sources in that section. As you zoom in closer and closer, the bins adapt to smaller cells until individual sources. See the online help for more information.
*If you have more than one catalog loaded, there is a corresponding color swatch in each catalog tab header to help you remember which catalog is which color in the overlays.
*These tools can now both read and write Parquet format catalogs.
*Myriad bugs have been squashed and miscellaneous infrastructure upgraded.

ZTF PUBLIC DATA RELEASE 22: Now available

The Zwicky Transient Facility (ZTF) and IPAC at the California Institute of Technology announce the twenty-second ZTF Public Data Release. ZTF is an optical time-domain survey covering the northern sky visible from Palomar Observatory since 17 March 2018. This release adds 4 months of observations to the twenty-first data release, up to 30 June 2024 for the public portion of the survey, and private survey time prior to 28 February 2023. The private surveys include observational programs awarded by Caltech or performed by the ZTF collaboration.

The products include 58.5 million single-exposure images, 177 thousand co-added images, accompanying source catalog files containing 888 billion source detections extracted from those images, and 4.92 billion light curves constructed from the single-exposure extractions.

A guide to ZTF Data Release 22, with data access instructions and supporting documentation, is available at https://irsa.ipac.caltech.edu/data/ZTF/docs/releases/ztf_release_notes_latest

Access to the data products is available via the on-line and API services of the NASA/IPAC Infrared Science Archive (IRSA) at https://irsa.ipac.caltech.edu/Missions/ztf.html

Note: transient alerts extracted from difference-images commenced public distribution on June 4, 2018. These alerts continue to be generated and distributed to brokers as the public survey proceeds. For further details and alert archive see https://ztf.uw.edu/alerts/public

ZTF is supported by the National Science Foundation under Grants No. AST-1440341 and AST-2034437 and a collaboration including current partners Caltech, IPAC, the Oskar Klein Center at Stockholm University, the University of Maryland, University of California Berkeley, the University of Wisconsin at Milwaukee, University of Warwick, Ruhr University, Cornell University, Northwestern University and Drexel University. Operations are conducted by COO, IPAC, and UW.
