ESO Complete In-house Re-processing of 20 Years of UVES 1D Spectra

Published: 26 Oct 2020

As part of ESO’s efforts to offer science data products to its community via the ESO Science Archive Facility, all the spectroscopic data acquired since the beginning of UVES operations at the VLT from March 2000 to March 2020, i.e. 20 years, have been reprocessed. Whenever possible, 1D spectra have been stacked at the OB level. The master calibrations associated with the science data before March 2015 have been reprocessed for better quality and consistency. Due to this reprocessing, some of the early science products not available before are now provided. All 1D spectra products are available from the ESO archive, have quality control plots and associated 2D extracted spectral images.

The UVES stacked 1D spectra products are built from single exposure 1D spectra, whose scientific quality is similar to that of the UVES products, which were previously available in the data stream. These single exposure 1D spectra products are now served on request as ancillary files.

The UVES reprocessed 1D spectra products can be discovered and downloaded via ASP or programmatically. More details are provided in the accompanying documentation.
