Appendix B: Scientific 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 Phase I proposal template. The science policies group will sort proposals according to the categories and keywords listed below. For additional information on the proposal sorting into each panel, see HST Proposal Selection Procedures. Please note Phase I keywords were revised and expanded slightly beginning with Cycle 28 to align with the Unified Astronomy Thesaurus.
