Hubble Space Telescope Call for Proposals for Cycle 11

8.16 Description of the Observations

---

(This is item 15 in the GO/SNAP template; it does not appear in the AR/Theory template.)

Please provide a short description of the proposed observations. Explain the amount of exposure time and number of orbits requested (e.g., number of objects, examples of exposure-time calculations and orbit estimates for some typical observations). You should summarize your target acquisition strategies and durations where relevant.

Discuss and justify any non-standard calibration requirements (see Section 4.3), if any. You should estimate the number of orbits required for these special calibrations, and include them in the OS (see Section 8.14).

Depending on the type of proposal, the following items should also be included:

• Long-term projects should provide summary information for the entire project, along with a cycle-by-cycle breakdown of the requested spacecraft orbits.
• Treasury Programs should discuss the data products that will be made available to the community, the method of dissemination, and a realistic time line. It is a requirement that data products be delivered to STScI in suitable digital formats for further dissemination via the HST Data Archive or related channels. Any required technical support from STScI and associated costs should be described in detail.
• Calibration and Innovative proposals should present a detailed justification of how they will achieve the goals of the program, and if applicable, a description of the conditions under which these goals will be achieved.
• Calibration proposals should discuss what documentation, and data products and/or software will be made available to STScI to support future observing programs.

There is no specific page limit for the Description of the Observations, but make sure that you do not exceed the total page limit for the proposal as a whole (see Section 7.1.2).
