Appendix B: Science Keywords
Keywords to be used in APT when submitting a proposal.
The Tables in this Appendix list the Scientific Keywords that are valid for use in the proposal template.
Within a panel, proposals are assigned to individual reviewers based on the reviewers' expertise and based partly on the keywords given in the proposal and partly on analysis of the proposal text. Generally, the more keywords the proposer selects the better the match to reviewers' expertise. Proposals can designate both a Science Category and an Alternate Category. Designating an Alternate Category enables usage of keywords from multiple categories. The Science Mission Office at STScI reserves the right to re-classify proposals.
For additional information on the proposal sorting into each panel, see HST Proposal Selection Procedures. The HST Scientific Categories and Keywords were developed using the Unified Astronomy Thesaurus beginning in Cycle 28.
