1st Generation Lesson Learned

Management and Contracts-Upfront R&D, Phase A added.- Agreement on use of Management Tools - More ESO-Consortium Partnership -Global approach (including operations), close involvement prior to PAE-Commissioning painful. Early science added. Early involvement Paranal

Technical Aspects- Instruments have too many modes.

- Positive overall evaluation of VLT (HW and SW) standards-Move towards pipelines which produce science products.

More than burst: Star Formation at high Z (Fosbury et al.)Emission line galaxies magnified by

an intervening cluster provide unique

information on star formation history

at early epochs. The Lynx galaxy was

studied at Keck with ESI and

NIRSPEC. Intermediate resolution

spectroscopy has provided line

intensities and kinematics. Used to

infer the properties of the ionizing

sources and abundances.Low spatial

density. Intermediate resolution,

spectral coverage from UV to IR required.
