ZTF DR1

[Graham, Matthew J.]

The Zwicky Transient Facility (ZTF)<https://www.ztf.caltech.edu/> and IPAC at the California Institute of Technology announce the first ZTF Public Data Release. ZTF is an optical time-domain survey covering the northern sky visible from Palomar Observatory. This release includes data products from the public portion of the survey spanning March to December, 2018. The products include ~3.4 million single-exposure images, ~102 thousand co-added images, accompanying source catalog files containing ~63 billion sources detected from those images, and ~2 billion lightcurves constructed from the single-exposure extractions. Note: transient alerts extracted from difference-images commenced public distribution on June 4, 2018. These alerts continue to be generated and distributed as the public survey proceeds.

A guide to ZTF Data Release 1, with data access instructions and supporting documentation is available at https://www.ztf.caltech.edu/page/dr1

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


ZTF is supported by the National Science Foundation and a collaboration including Caltech, IPAC, the Weizmann Institute for Science, the Oskar Klein Center at Stockholm University, the University of Maryland, the University of Washington, Deutsches Elektronen-Synchrotron and Humboldt University, Los Alamos National Laboratories, the TANGO Consortium of Taiwan, the University of Wisconsin at Milwaukee, and Lawrence Berkeley National Laboratories. Operations are conducted by COO, IPAC, and UW.
