Abstract / Description of output
The VDFS comprises the system to pipeline process and archive the data
from infrared observations taken by both the WFCAM instrument on UKIRT
and the forthcoming VISTA telescope. These include the largest near-IR
surveys to date, such as UKIDSS, which produce terabyte sized catalogues
of over 10^9 rows. Such large data volumes present a performance
challenge when the catalogue data, stored in a relational database,
require many iterations of astrometric and photometric recalibration.
Here we present the VDFS recalibration solution that will be employed in
the WSA from the forthcoming UKIDSS Data Release 4 and VSA from its
inception.
