Abstract:
The VVV survey targets the galactic bulge and a piece of the adjacent
plane in Z, Y, J, H, and Ks. The total area of this survey is 520 square
degrees and contains 355 open and 33 globular clusters. The VVV is
multi-epoch in nature in order to detect a large number of variable
objects and will provide > 100 carefully spaced observations for each
tile. 5-sigma detection limits are Z=21.9, Y=21.2, J=20.2, H=18.2, Ks=18.1.
These will be used to create a 3-dimensional map of the Bulge from
well-understood distance indicators such as RR Lyrae stars. Other
science drivers include the ages of stellar populations, globular
cluster evolution, as well as the stellar initial mass function.
The VVV Survey data delivered in this part of ESO Data Release 1 (DR1)
includes the VISTA/VIRCAM paw-print and tile images that were acquired
until September 30, 2010, and processed by the Cambridge Astronomical
Survey Unit (CASU). This VVV_CAT data release contains the single-epoch
band-merged (Z,Y,J,H,Ks) catalogues associated with the VVV tile images
that have already been released in the part of DR1 identified as VVV in
the ESO archive. VVV_CAT contains 269 tile catalogues.
Data origin:
Data originate from the ESO Science Archive Facility and went through
the Phase 3 content validation process.

--------------------------------------------------------------------------------
Note (1): Primary sources have priOrSec=0 OR priOrSec=frameSetID
Note (2): We recommend that users should restrict their analysis to objects
with zpErrBits, ypErrBits, etc<255 at all times and zpErrBits=0 if they
require the most reliable subset of the sources. Values of zpErrBits=16
indicate that the source was deblended, zpErrBits=64 that at least one bad
pixel was within the default aperture and zpErrBits=128 that the source was
low confidence within the default aperture."
