Abstract:

The ISOCAM infrared camera is one of the four instruments on board the ISO (Infrared Space Observatory) spacecraft which was launched successfully on 1995 November 17. It operates in the 2.5 - 18 $\mu$m range, and was developed by the ISOCAM consortium lead by the French Service d'Astrophysique of CEA Saclay. This paper presents different algorithms which can be used for the calibration of ISOCAM data. Advantages and limitations of each method are also outlined. A range of examples illustrates the results.
