The long-term monitoring of the spectrophotometric IUE standard starsFor more than twelve years the International Ultraviolet Explorer (IUE) satellite has consistently monitored about 44 spectrophotometric standard stars. This monitoring program was set up mostly to fit some particular needs of the IUE mission, such as the study of the detector linearity, sensitivity, degradation, and scattered light profiles. The impressive body of data accumulated over the years of about 7000 images, is unique and particularly suited for stellar studies on the stars themselves. The most frequently observed early type stars used as baseline calibration standards are studied. Part of what has been learnt about the cameras from studies of these spectral images and which has indirectly affected most of the published studies is presented. Possible improvements in flux accuracy which will be incorporated in the IUE final archives are discussed.
