Release of XSHOOTER science data products

Published: 19 May 2014

The ESO archive now provides access to reduced scientific data obtained with the XSHOOTER spectrograph mounted on the VLT.

33000 spectra of all kinds of sources obtained in "ECHELLE,SLIT mode" from the begin of operations in October 2009 until the end of 2013 are now published. The data consist of extracted, wavelength-calibrated and flux-calibrated 1-dimensional spectra in tabular format following the established standard for ESO science data products. There is normally one spectrum for each of the three XSHOOTER arms (UVB, VIS, NIR). When downloaded, each spectrum comes with ancillary information related to quality control and observational circumstances, and with a preview plot.

The XSHOOTER data collection will grow with time and includes the current stream of XSHOOTER data as they are acquired at the observatory, with the reduced products becoming available in monthly release cycles as soon as they are processed. The data products, being tagged "XSHOOTER_ECHELLE", 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 fields specific to harvest spectral data.

More details about the data can be found in the associated Phase 3 data release description for XSHOOTER data.

Instructions on how to read or display data in this ESO data format can be found in the 1d spectrum data format help page.
