12.13 Cycle 25 Calibration Program
The Cycle 25 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 25 is listed in Table 12.15. Programs were also included to calibrate cenwaves G140L/800 and G160M/1533; they are listed in Table 12.16.
