12.9 Cycle 21 Calibration Program

The Cycle 21 calibration program continued the routine calibration and monitoring observations performed in Cycle 20, including long-term programs to monitor the sensitivity and wavelength scale of both the FUV and NUV detectors. Brief descriptions of these monitoring programs are presented in Table 12.2. Table 12.9 lists additional special calibration programs that were undertaken in Cycle 21.
