Multiwavelength astronomy using ESIS

Abstract

We present results on multi-frequency astronomy obtained using the European Space Information System, ESIS. ESIS is an ESA service designed to access, manipulate and combine archival data from a number of remote archives in the fields of Astronomy and Space Physics. The examples presented here include plots of radio-to-X-ray energy distribution of Active Galactic Nuclei, spectrograms of IUE/UV data, direct comparison of images from different experiments and overlay of catalogue sources on image data. The ESIS project is currently reaching the end of its pilot phase. Its services will be available to the general astronomical community in 1993.
