SCIENCE
The TOP LEVEL REQUIREMENTS for CUBES are motivated mainly by the cases outlined below, where a significant gain in sensitivity and spectral resolution in the ground UV will provide a unique capability for years to come. Although the design is motivated by these cases, we envisage CUBES as a chance to open-up new parameter space at Paranal, with the expectation of a much broader range of scientific applications and with a diverse user community.
