... The time taken to read through a quadrant on the array sets a fundamental limit on the fastest electron collection rate which can be achieved by resetting all the pixels. An inherent consequence of the methods of operating the NICMOS array detectors in the ACCUM, MULTIACCUM, and RAMP modes is therefore that there is a minimum possible exposure time, ~ 0.6 seconds (0.302 for MULTIACCUM), set by the time required to read the array. ... Figure 15.1 illustrates the operation of bright object mode. ...
