1.4 Proposal Preparations and Observations with STIS

Use the STIS Instrument Handbook together with the Cycle 28 HST Call for Proposals (CP) and HST Primer when assembling your STIS Phase I proposal. The CP provides policy and instructions for proposing. The HST Primer provides a basic introduction to the technical aspects of HST and its instruments, and explains how to calculate the appropriate number of orbits for your Phase I observing time requests. The STIS Instrument Handbook contains technical information about STIS describing its expected performance and presenting suggestions for use. Chapter 2 describes special considerations for Cycle 28.

If your Phase I proposal is accepted, you will be asked to submit a Phase II proposal in which you specify the exact configurations, exposure times, and sequences of observations that STIS and the telescope should perform. To assemble your Phase II proposal, use the STIS Instrument Handbook in conjunction with the Phase II Proposal Instructions. These instructions describe the exact rules and syntax that apply to the planning and scheduling of STIS observations and provide relevant observatory information. You should also check the STIS website for any updates relevant to the current proposal Cycle. Many other useful HST documents are also available on-line at:

1.4.1 The STIS Team at STScI

STScI has a team of Instrument Scientists, Scientific Programmers, and Research and Instrument Analysts who support the development, operation, and calibration of STIS Instrument. This team is also responsible for supporting STIS users. Furthermore, the team provides archival support for the heritage instrument, GHRS.
