The ESO Phase 3 Process

The so-called Phase 3 is the process of preparation, validation and ingestion of science data product (SDP) for storage in the ESO science archive facility, and subsequent data pubblication to the science community. These SDPs are data products with instrument and atmospheric signatures removed, calibrated in physical units, and with noise properties quantified and documented.

To ensure the successful integration of SDPs into the archive, ESO supports the users in carrying out the Phase 3 process by defining ESO/SDP data standards, by devising procedures and providing the infrastructure for the delivery of the SDPs, and by supplying tools for the data preparation.
