Notes et articles sur la correction des transitoires de la caméra infrarouge LW-CAM embarquée sur le satellite ISO

Les documents ci-dessous ont été formatés en LaTeX --> dvi --> PostScript, la conversion vers le PDF n'étant faite qu'après. Pour obtenir des documents de qualité d'impression maximale, si vous le pouvez (visualiseurs GV ou GhostScript, imprimantes PS), privilégiez le PostScript !

En attendant que je prenne le temps de poser ici les entrées BibTeX de chacun des articles, vous pouvez les trouver toutes rassemblées dans un seul fichier ou bien vous pouvez faire une requête sur ADS pour choisir le format bibliographique qui vous convient.

Cette liste est partielle. Manque au moins : ceci et le livre ISO-CAM et un article sur le traitement de cartes Spitzer 180 um présenté au GRETSI 2005 (Th. Rodet et al.).

• The importance of ground based tests for space experiments using low background IR photodetectors

  Local summary : This paper reviews the behavior of most of the ISO systems (CAM, PHT, LWS and SWS) and detectors. Several possible causes of problems are considered, in optical, electronical and detectors sub-systems. We explain that, since the transients are reproducible and the glitches (related to hit of high energetic particles), if all other parts (optical, electonic, temperature control, ...) are without missconception, the transient models ensure that glitches appear to be the only limiting factor. We explain also how to check such whole system with the help of the detector transients during ground based tests. This paper may be useful for any team currently involved with development of such system.

  Local summary : This paper is an overview of transient models for most Si:Ga and Ge:Ga detectors on-board the ISO satellite. We focused on the applications of physical models provided by Fouks' theory. This paper should be useful for SIRTF (MIPS), Astro-F (FIR) and Herschel satellites to begin as soon as possible to consider the use of physical models in order to remove the transient effects in they Ge:Ga detectors.

  Local summary : This paper presents briefly the current status of the modelization of point source transients for ISOCAM (Si:Ga detector). Even the model is highly accurates, the correction method is not trivial. We show adjustements and explain the limits of the new model for point sources and of the current correction method.
