Abstract

The joint archive facility of the European Southern Observatory (ESO) and the Space Telescope - European Coordinating Facility (ST-ECF) is undertaking particular efforts in the field of associating (grouping) Hubble Space Telescope (HST) observations for a number of years already. By now their users are given means for browsing associations of HST images. Soon the same capability will be provided for spectra as well. Associations of observations can either be defined and driven by requirements imposed by higher level algorithms like co-adding and drizzling techniques or by user defined constraints. In any case we consider these services an important precursor and testbed to a future virtual observatory. Two components complement an on-line interface (archive.eso.org) to such data products: For one part it is the selection process which can be greatly improved by adding preview capabilities for individual or multiple exposures. On the other hand it requires a request handling system which supports the concept of associations and which can expand a given association and computes and delivers calibrated and combined data products.
