Phase 2 Proposal Instructions for Cycle 10

3.3 Target Description [Description]

---

A target description must be provided for each target. The Target Description will be one of the key fields used by archival researchers in searching through the HST data archive; thus it is extremely important that the information be filled out completely and accurately for each target.

Each target must be assigned a single primary category from Table 3.2, and at least one descriptive keyword, chosen from the appropriate Table 3.3 through Table 3.9 (see Table 3.2 for which table is appropriate for each category). The discrete features and descriptors in Table 3.10 may be used as descriptive keywords for any category. A maximum of five descriptive keywords may be specified.

It is possible, but not required, to specify a second category for a target, followed by one to five descriptive keywords from the appropriate tables, as described for the primary category.

Whether one or two categories are used, all values must be separated from each other by commas. For example, suppose the STAR category is chosen with the descriptive keywords Polar and Interacting Binary. This target description would be specified as STAR, Polar, Interacting Binary.

The categories in Table 3.2, and some of the descriptive keywords in Table 3.3 through Table 3.10, are followed by explanatory text in parentheses. This text is provided only for explanatory purposes and is not part of the category or keyword itself. Only the non-parenthesized portion, which appears in bold in the tables, should be entered into the RPS2 file.
