4.1.4.5 Off-nominal Measurements

 The various device performance, spectral resolution and quantum efficiency measurements to be made, and the associated off-nominal conditions for the measurements, are summarized in Table 4.3. The ``CCD parameters'' referred to in Table 4.3 will be measured according to procedures specified in the ACIS CCD Screening Plan (ACIS memo PS-77). Thus the results of these measurements will be determination of quantities such as noise, dark current, and charge transfer efficiency, for each `off-nominal' condition listed in Table 4.3.
