Dear CFHTLS users,

At the request of CFHT Science Advisory Committee TERAPIX and CADC agreed to release “candidate” or “pre-release” data products that are not yet in their final form. This "release candidate" are partial datasets that concern the DEEP and the WIDE data obtained between June 1st, 2003 and September 5 2005.

The the Pre-w and the Very Wide components of the survey will be made available in the coming weeks. The stacks and catalogues were produced for the DEEP and WIDE fields in u,r,g,i,z at TERAPIX and are available from the Canadian Astronomy Data Centre (CADC) exclusively to authorized CFHTLS users.

Location: You can find TERAPIX stacks and catalogues for the four DEEP fields (all in u,g,r,i,z) and the three WIDE fields (some in u,g,r,i,z, some in g,r,i and some in i only, depending on the progress of the survey in each filter) at this address: at CADC

Information: Individual u,g,r,i, and z stacks and catalogues, chi2 images and catalogues as well as quality assessement data ohn the DEEP and WIDE are available. Some useful information about the Deep data can be found here. Most information is useful for the Wide as well (Other pages for the Wde will be available soon).

Validation: These data have been fully validated by TERAPIX and are suitable for scientific exploitation. It is expected that the final "full release" dataset provided will be almost identical to these stacks and catalogues. More details about the DEEP and WIDE data will be available soon on the terapix pages.

Please feel free to retrieve these data and experiment with them. Any comments and suggestions regarding this T0003 "release candidate" or the distribution system should be sent to terapix@iap.fr and to cadc@hia.nrc.ca.

Happy exploring!

TERAPIX and CADC
