The Catalina Surveys
Data Release 1 (CSDR1)


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

Top News: View ~12,000 RR Lyrae from the Catalina Surveys Data Release 1.
CSDR2 coming soon!

    Introduction

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

    The research of CSS involves searches for rapidly moving Near Earth Objects (NEOs) whereas that of CRTS involves the detection of 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 archival data service.

    Data Available in CSDR1

    Here you will find the first public data release (CSDR1) from the Catalina Surveys that consists of all photometry from seven years of photometry taken with the CSS Schmidt telescope. This data release encompasses the photometry for 198 million objects with V magnitudes between 12 and 20 from an area of 24,000 square degrees. The sky coverage and number of observation epochs at each location is as shown here:


      An Aitoff projection of the sky region covered by this release in equatorial coordinates (centered at RA=0h). The colour key gives the number of epochs at each location.

    Data Access

    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.
