Descriptions
Abstract: This is the release of reduced spectra from the high-resolution echelle spectrograph ESPRESSO. This release is an open stream release. It is complete from start of operations on 24th October 2018 until present. Data content is not fixed but grows with time as new data are being acquired and processed (approximately with monthly cadence and with a delay of one to two months). Data have been reduced using the ESPRESSO pipeline version 2.2.1 or higher. It includes extraction of the spectrum, flat fielding, wavelength calibration, and flux calibration. Sky subtraction is only performed if fibre B is placed on sky. If the science target is not a QSO then an automated cross correlation with a stellar reference mask is executed in order to calculate the radial velocity (RV) of the observed object. Please note that systematic shifts of the RV values can occur between different versions of the pipeline. It is highly recommended to use only products from the same pipeline version for RV studies.
Other: This is a dynamic dataset; it is growing as new data is added. The DOI refers to the newest available dataset.
