The science use cases describe representative programs that might be carried out on GMT or TMT. The format is provided by a template that resembles a typical observing time proposal. Anyone preparing a use case should follow the template as much as possible. Do not worry about getting the technical details exactly right; the emphasis in the use cases is on the science and not on the precise number of nights required. Speakers’ presentations should cover the material in the template, with the emphasis on the science. Participants are strongly encouraged to deliver their use case documents to the organizers by the end of the workshop!
Some examples provided by the GSMT Science Working Group can be used as guidance:
Written use cases based on presentations at the June 2008 workshop in Chicago, alphabetized by PI:

Information on the baseline operations plans for both facilities is also provided. Unlike real observing proposals, it is possible to request operational modes not included in the baseline plans—but the use case must provide a clear and compelling justification for such modes.
At the present time, a set of integration time calculators is not available. The best approach is usually to use estimates for comparable instruments elsewhere (e.g., Gemini, Keck, Magellan, VLT) and then scale appropriately for aperture, pixel scale, spectral resolution, and Strehl. Some tabular information is provided on the technical information page referenced above.
