Abstract
An overview is given of the absolute flux calibration of the ISOCAM detecto rs. The flux calibration is based on observations of standard stars selecte d from the Ground Based Preparatory Programme, for which Kurucz stellar mod els are available. No dependencies of the responsivity on different configu rations of the camera were found. No trend of changing responsivity is foun d throughout the mission for the SW and LW detectors. There exists a decrea sing responsivity of about 5% for LW during the orbit.
