FREQUENTLY-ASKED QUESTIONS ABOUT FOUKS MODELS AND TRANSIENT CORRECTION METHODS FOR THE ISOCAM LW DETECTOR

摘要

At low temperature and for very low (astrophysical) incoming flux, most of the IR detectors are affected by transient response, which delays the response and can strongly bias the estimated flux. The LW detector of ISOCAM is also affected by such behaviour. It has been shown that an important component of the transient effects of this detector can be described with high accuracy using a non-linear and non-symmetrical model based on pure physics. An inversion method is also available. In this paper, we review the limitations of this model and the known problems occurring with the correction method, and we give advice on how to process the data.
