The Cycle 21 calibration plans for COS (see Table 12.7) will continue the routine calibration and monitoring observations performed in Cycles 17–20. The priorities assigned to the calibration of various COS modes will be determined by the approved GO programs in each cycle.
If your program requires calibrations beyond those beyond those described here, then you should explicitly include this calibration in your Phase I proposal.Table 12.7: Cycle 21 Calibration Programs
