		| Abstract: | 
		A significant fraction of observing time on ESO's new Very Large Telescope will be spent in service mode; therefore, investigators need to describe in detail what they want to observe, and how. ESO is prototyping a distributed ``Phase II'' system that will allow astronomers to prepare their observations at their home institutions, while maintaining a central repository for all observation data. Astronomers will be offered a wide array of observation preparation tools, including data entry GUIs, instrument simulators, and catalog interfaces. The system is structured as a set of distributed clients and centralized servers, and it operates as a front-end to the other elements of the VLT Data Flow System. |
