Paper Abstract

The International Ultraviolet Explorer (IUE) is a scientific satellite operated in re Al time to obtain ultraviolet spectra of astronomical objects in the wavelength range 1000 Å ≤ λ ≤ 3200 Å in either of two selectable dispersion modes. IUE spectra are recorded by SEC vidicon cameras and transmitted digitally to a ground station as two-dimensional images. The reduction of these data begins with the International Ultraviolet Explorer Spectral Image Processing System (IUESIPS), an on-line interactive image processing system which has been in operation for one year. The task of IUESIPS is to remove all known instrumental effects from IUE spectral images and to provide, in a timely fashion, IUE Guest Observers with reduced data - in the form of spectral intensity as a function of wavelength - amenable to immediate astronomical analysis. The current status of this image processing system is discussed and the types of reduction operations which are routinely performed are presented along with the known existing limitations of the system.
