Main Toolbox components
31 Science cases including 7 “prominent” onesprioritized Telescope & Instrument requirements
a timed 12-Instrument suite covering science cases requirements on Telescope, AO & Siteassessment of technology, complexity, cost & risk
a roadmap for the ~5 AO systems required requirements on Telescope, Instruments & Site AO/LGS concepts & technological pathfinders
Site parameters evaluation & observing impact
Telescope Design families evaluation

E-ELT Top Level Science Requirements
a general-use multi-purpose facility(last-hour multi-telescope alternative opened)
an efficient improved-seeing “wide-field” facility(down to visual wavelengths)
an Instrument-friendly facility
