The ESO Science Archive Facility has distributed raw calibration files such as bias frames and flat field frames for many years. As an additional service, we now are also distributing certified, processed and co-added calibration frames that can directly be used for science processing without having to run the entire data reduction chain. Processed calibrations are certified for quality and typically become available two-three working days after being acquired at the telescope to allow for such a certification. The certification process also applies to the raw calibration files and, e.g., ESOReflex data reduction workflows can be used to customize the generation of the processed and co-added calibration frames and to apply them to the science files.

The Archive Science group has now published a user guide with the description of the reduced data product types that can be browsed and downloaded from the dedicated Phase 3 query forms of the ESO SAF. The user guide contains an overview of the data types, a description of their reduction/calibration levels and instructions on how to browse and access these products.

New data products resulting from the ESO/VST Public Survey VPHAS+ are now available via the dedicated Phase 3 query interface at the ESO Science Archive Facility.

All spectra obtained with the spectrograph FLAMES/GIRAFFE in the MEDUSA mode from June 2005 till December 2014 are now published via the ESO archive as reduced data. The extracted, wavelength calibrated, one-dimensional spectra are in tabular FITS format, see the ESO science data products standard for a description of the data format and metadata information. Their wavelength scale is in the heliocentric reference system. All 1D-spectra come with error estimates and signal-to-noise ratio per wavelength bin. There are a number of files associated at download time to each spectrum, including sky spectra when available. The GIRAFFE_MEDUSA data collection will grow with time, with new reduced spectra being added with monthly cadence. FLAMES GIRAFFE spectra acquired before June 2005 will also soon be added to the collection. The 1D spectra tagged "GIRAFFE_MEDUSA", can be queried and downloaded using the Phase 3 generic query form that provides access to all Phase 3 data or the Phase 3 query form dedicated to spectral data with query parameters suited to harvest spectral data.

ESO one-dimensional (1D) spectra in tabular FITS format can now be displayed and processed with IRAF using the external package SPTABLE, thanks to a close collaboration between ESO and the IRAF developers. The popular IRAF ONEDSPEC package, including SPLOT, and the IRAF RV package are now able to process the 1D spectra from the spectroscopic ESO Public Surveys (PESSTO and Gaia-ESO), Large Programmes (ESSENCE, GOODS FORS2+VIMOS, and zCOSMOS) and internal data products (UVES ECHELLE, XSHOOTER ECHELLE, HARPS, soon GIRAFFE, etc.).

VIDEO is a deep near-infrared survey which targets ~12 square degrees over the ELAIS-S1, XMMLSS, and ECDFS extragalactic fields. VIDEO belongs to the suite of six public surveys being conducted at ESO’s Visible and Infrared Survey Telescope for Astronomy (VISTA).

The VISTA Variables in the Via Lactea Survey (VVV) is a wide area, near-infrared, multi-epoch imaging survey of the Milky Way bulge and disk. The initial survey in the five broadband filters Z, Y, J, H, Ks for a total sky coverage of 540 sq deg, is followed by extensive multi-epoch observations in the Ks band.
