Abstract / Description of output
The VISTA Data Flow System comprises nightly pipeline and archiving of
near infrared data from UKIRT-WFCAM and VISTA. This includes multi-epoch
data which can be used to find moving and variable objects. We have
developed a new model for archiving these data which gives the user an
extremely flexible and reliable data set that is easy to query through
an SQL interface. We have introduced several new database tables into
our schema for deep/synoptic datasets. We have also developed a set of
curation procedures, which give additional quality control and
automation. We discuss the methods used and show some example data. Our
design is particularly effective on correlated data-sets, where the
observations in different filters are synchronised. It is scalable to
large VISTA datasets which will be observed in the next few years and to
future surveys such as Pan-STARRS and LSST.
