HST may be forced to switch from three-gyro to two-gyro mode operations during the course of Cycle 14. This will impact both scheduling efficiency and scientific performance. A number of changes have been instituted in both the proposal format and the review process to take this eventuality into account. HST web pages and documents, such as the Call for Proposals, the HST Primer, and the Instrument Handbooks, use the symbol at the left to indicate that the material contained therein may be affected by two-gyro operations. Readers should consult the Two-Gyro Handbook (this document) or the HST Two-Gyro Science Web Page for information about two-gyro mode operations.
