... Because of the effects of shading, and the possibility that the underlying dark current may vary with time since reset, the removal of dark current (for calibration purposes, we implicitly assume shading and amplifier glow is a part of the time variable "dark current") from data is more complicated than for many other instruments. The most accurate way to remove the dark current from any observation is a measurement of the dark current with an identical integration time. ...
