CDS participates in the data release of the final version of the
Canada-France-Hawaii Telescope Legacy Survey (CFHTLS), a multi-color
collection of data obtained over 6 years from the summit of Mauna Kea.
As released, the Legacy Survey is composed of more than 15,000
individual images of the MegaCam camera, each image represents nearly 1
gigabyte of data. The five color-band cover the optical domain from blue
to red, including near-ultraviolet and near-infrared. The large amount
of data generated at the telescope over the years was processed at
Terapix (Institut d'Astrophysique de Paris, UMR
7095, UPMC and CNRS INSU), the curator of the CFHTLS, which
characterized and optimized the data set based on individual images
calibrated by CFHT. Their main product consists in a series of
catalogues of some 38 millions objects. The data products are made
available from the Canadian Astronomy Data Centre
(CADC, NRC) and through the
CDS services. Searchable catalogues are made available through VizieR,
and the survey images can be explored through Aladin.
