Abstract: This is the release of reduced spectra from the FORS2 - the visual and near-UV FOcal Reducer and low dispersion Spectrograph 2 for the Very Large Telescope (VLT) of the European Southern Observatory (ESO). Data of the three spectroscopic modes of FORS2 are included in this release: long-slit spectroscopy (LSS) using a mask with 6.8′ long slits of different widths, and multi-object spectroscopy with movable slit blades (MOS, slit length about 20′′) or with masks (MXU, arbitrary slit length). The spectra are taken using a wide variety of grisms with different wavelength ranges and dispersions. They include a set of normal grisms, which cover the full operational wavelength range of FORS2 with essentially three different dispersions (230 Å/mm, 110 Å/mm, and 45 to 50 Å/mm) and medium resolution, high throughput holographic grisms, which are based on volume-phased holographic gratings cemented between two glass prisms.
Other: This is a dynamic dataset; it is growing as new data is added. The DOI refers to the newest available dataset.
