(a) Relationship between offset and digital levels for different gains with a pixel dwell time of 10.04 µs. (◆) Gain of 7; (■) gain of 8; (▲) gain of 9; (●) gain of 10. The solid lines are the linear regression for each gain. (b) Variation of digital level with time for a gain of 8 and a pixel dwell time of 10.08 µs. The data were collected for each offset value on the same day with 4 hour intervals and also on 3 different days of the week. (C) Variation of the digital level values as a function of time for offsets of 127 (◆) and 128 (■) for a gain of 8.4 and a pixel dwell time of 10.04 µs.
