12.12 Cycle 24 Calibration Program

«Previous Next»

The Cycle 24 calibration plans for COS continued the routine calibration and monitoring programs performed in previous Cycles. Brief descriptions of the programs are listed in Table 12.2. The full calibration plan for Cycle 24 is listed in Table 12.13.

The program also included enabling and calibration programs designed to facilitate the move to Lifetime Position 4 LP4); they are listed in Table 12.14.
