Near Infrared Camera and Multi-Object Spectrometer Instrument Handbook for Cycle 17

	We anticipate that all HST observations in Cycle 17 will be undertaken in the Three-Gyro Science Mode, providing greater scheduling flexibility and greater sky coverage (at any epoch) than in Cycles 14, 15 and 16. Proposers should plan their observations accordingly, using the Target Availability Table in the Primer (Table 6.1) and the visibility tools on the HST Phase I Proposal Roadmap Web site.
