XSHOOTER ECHELLE pipeline-reduced spectroscopic data

This is the release of reduced 1D spectra from the XSHOOTER spectrograph, ECHELLE (SLIT) mode (as opposed to the IFU mode which is not included). All spectra have been reduced under the assumption of point-like sources. This release is an open stream release, it includes so far archived XSHOOTER data and will be continued into the future. The processing scheme is as homogeneous as possible. The selected data cover the vast majority of the entire XSHOOTER data archive, from the begin of operations in October 2009 until present.
