Abstract:
The VVV Survey data delivered in this part of ESO Data Release 2 (DR2)
are based on the VISTA/VIRCAM images that were acquired up to
September 30, 2011, 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 DR2 identified
as Batch 2 of the "VVV' collection in the ESO archive.
VVV_CAT contains 348 tile catalogues.
Description:
The J, H and Ks images for each tile were obtained contemporaneously
within a single OB, so that the time interval between images in
different filters does not exceed 20 minutes. The Z and Y images for
each tile were grouped together in another OB, separate in time from
the JHKs OBs.

--------------------------------------------------------------------------------
Note (1): Primary sources have priOrSec=0 OR pri0rSec=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.
