Abstract:
We present observations collected in the CFHTLS-VIPERS region in the
ultraviolet with the GALEX satellite (far- and near-ultraviolet
channels) and in the near-infrared with the CFHT/WIRCam camera (Ks
band) over an area of 22 and 27deg^2^, respectively. The depth of the
photometry was optimised to measure the physical properties (e.g.,
star formation rate, stellar masses) of all the galaxies in the VIPERS
spectroscopic survey. The large volume explored by VIPERS will enable
a unique investigation of the relationship between the galaxy
properties and their environment (density field and cosmic web) at
high redshift (0.5<=z<=1.2).
In this paper, we present the observations, the data reductions, and
the build-up of the multi-colour catalogues. The CFHTLS-T0007
(gri-chi^2^) images are used as reference to detect and measure the
Ks -band photometry, while the T0007 u*-selected sources are used as
priors to perform the GALEX photometry based on a dedicated software
(EMphot). Our final sample reaches NUV_AB_ 25 (at 5sigma) and
K_AB_ 22 (at 3sigma). The large spectroscopic sample ( 51,000
spectroscopic redshifts) allows us to highlight the robustness of our
star/galaxy separation and the reliability of our photometric
redshifts with a typical accuracy of sigma]_z_<=0:04 and a fraction
of catastrophic failures eta<=2% down to i 23. We present various
tests on the Ks -band completeness and photometric redshift accuracy
by comparing our results with existing overlapping deep photometric
catalogues. Finally, we discuss the BzK sample of passive and active
galaxies at high redshift and the evolution of galaxy morphology in
the (NUV-r) vs (r-Ks) diagram at low redshift (z<=0.25) based on the
high image quality of the CFHTLS. The images, catalogues, and
photometric redshifts for 1.5 million sources (down to NUV<=25 union
Ks<=22) are released and available at this URL:

Description:
The Canada-France-Hawaii Telescope Legacy Survey (CFHTLS) is an
imaging survey performed with Mega-Cam in five optical bands u*, g, r,
i, z. we use the images and photometric catalogues of the W1 and W4
fields from the worldwide T00073 release produced by TERAPIX4.
Since 2010, we have conducted a Ks-band follow-up of the VIPERS fields
with the WIRCam instrument at CFHT. The original motivation was to
guarantee an almost complete detection in Ks band of the VIPERS
spectroscopic galaxies.
