Space Telescope Science Institute   7.5 A Road Map for Optimizing Observations  7.6.1 WFC Gain

7.6 CCD Gain Selection


As quantified in Table 4.2 both the WFC and HRC CCDs have selectable gain values near 1, 2, 4, and 8 electrons per digital number. Various factors should influence the gain selected in Phase II for your science program: level of support and calibrations provided, influence of associated readout noise on data quality, dynamic range on the bright end, and data compressibility for WFC in limited applications.
