Paper Abstract

The European Southern Observatory Science Archive Facility is evolving from an archive containing predominantly raw data into a resource also offering science-grade data products for immediate analysis and prompt interpretation. New products originate from two different sources. On the one hand Principal Investigators of Public Surveys and other programmes reduce the raw observational data and return their products using the so-called Phase 3 - a process that extends the Data Flow System after proposal submission (Phase 1) and detailed specification of the observations (Phase 2). On the other hand raw data of selected instruments and modes are uniformly processed in-house, independently of the original science goal. Current data products assets in the ESO science archive facility include calibrated images and spectra, as well as catalogues, for a total volume in excess of 16 TB and increasing. Images alone cover more than 4500 square degrees in the NIR bands and 2400 square degrees in the optical bands; over 85000 individually searchable spectra are already available in the spectroscopic data collection. In this paper we review the evolution of the ESO science archive facility content, illustrate the data access by the community, give an overview of the implemented processes and the role of the associated data standard.
