The ESO Phase 3 process has been devised to manage the reception and
validation of survey data products, to ingest them into the ESO
archive and to publish them to the user community. The implementation
of the Phase 3 concept for catalogue data includes a dedicated
web-based user interface, the “Catalogue Facility”, which complements
the existing functionalities of the ESO archive by adding powerful
capabilities to query catalogue data by position or using other
non-positional constraints.
