Chapter 11:
COS in Phase II


11.1 Essential Program Information
11.2 A "Roadmap" for Phase II Program Preparation
11.3 Get the Tools and Rules
11.4 Specify Instrument Usage Particulars
    11.4.1 Gather essential target information
    11.4.2 Assess target acquisition strategies
    11.4.3 Determine the science exposure needs
11.5 Recap of COS Optional Parameters

The Phase II Proposal Instructions define the capabilities of HST. Therefore those Instructions take precedence over this Handbook if there is any conflict of information.

This chapter describes how to write a Phase II program to observe with COS and how to specify the Optional Parameters that are available. In Phase I, you submit a proposal to use HST. If approved, that then becomes a Phase II program, and you need to provide complete details to ensure your observations produce the results you want.
