12.10 Cycle 22 Calibration Program

The Cycle 22 calibration plans for COS (see Table 12.10) continued the routine calibration and monitoring observations performed in Cycles 17–21. Brief descriptions of these monitoring programs are presented in Table 12.2.

The program also included enabling and calibration programs designed to facilitate the move to Lifetime Position 3 (LP3).
