The Catalina Surveys
Data Release 2 (CSDR2)


Welcome to the second data release from the Catalina Surveys Team.

    Find out what's new about CSDR2.
    Update: data taken between 2012-11-01 and 2013-04-01 has been added.

    Introduction

    The Catalina Surveys consist of the Catalina Sky Survey (CSS) and the Catalina Real-time Transient Survey (CRTS).

    The CSS project involves searches for rapidly moving Near Earth Objects (NEOs), while CRTS searches for stationary optical transients (OTs). Both surveys work collaboratively to extract the maximum scientific return from data from three telescopes operated by CSS. In this same collaborative spirit we are now providing an open-access to all the archival photometry.

    Data Available in CSDR2

    Here you will find the second public data release (CSDR2) from the Catalina Surveys that consists of all photometry from seven years of photometry taken with the the CSS telescopes. This data release encompasses the photometry for 500 million objects (~40 billion measurements) with V magnitudes between 11.5 and 21.5 from an area of 33,000 square degrees. Catalina photometry covers objects in the range -75° < Dec < 70° and |b| > ~15° with the number of observation epochs at each location is as shown above (see FAQ). Catalina images will be available in the third data release.

    Disclaimer, Conditions, and Limitations

    This data is supplied with the intent of maximizing scientific utility. Although we have attempted to verify the integtrity of the data, users should be cautious with interpetration of measurements (as outlined in the FAQ). Wherever possible and appropriate, discoveries made using this data should cite the Catalina Surveys ID given by the services.

    This data is not being supplied by a data center. Therefore, we must limit queries by single users so that all users can benefit. Users wishing to run scripts with very large number of queries, or produce external services linking to the data, must contact us before doing so.
