The mean VISTA data volumes are high (estimated ~315GigaByte on
a typical night). Individual pawprints extracted from the ESO archive
can be passed through a calibration pipeline at Garching that will
remove instrumental artefacts, and produce astrometrically and photometrically
calibrated single pawprints for the user.
The UK-based VISTA Data Flow System (VDFS) receives a copy of all
VISTA raw data by agreement with ESO, and is required to fully respect
the proprietary rights assigned by ESO to observations. The VDFS
will further combine the pawprints into tiles, extract sources and
place these in a VISTA Science Archive where authorised users can
interrogate the data and use tools to combine it into survey products.
[This sytem is an evolution of that for WFCAM data - including the
surveys which ESO members are entitled to access via the WFCAM
Note that data processing by the UK VDFS is not a right (i.e. there
is no obligation on the UK to provide this outside the UK) but nevertheless
the UK VDFS will process data for others in a spirit of scientific
collaboration and public surveys, subject to availability of resources.
VISTA users wishing to make use of the UK-based VDFS to handle their
survey data processing needs should contact the VDFS
project leader to let VDFS know your plans so VDFS can comment
on them to avoid mistakes/ misunderstandings.
ESO requires all final Public Survey data products to be delivered
to ESO for integration into the ESO archive.
Note that (by default) ESO expect Public survey data to be world
public when it is released, as is currently the policy for their
