Overview of the Mikulski Archive for Space Telescopes for the James Webb Space Telescope data archiving

摘要

In this paper we present the envisaged setup and changes to the current Mikulski Archive for Space Telescopes (MAST) configuration at the beginning of operations for the James Webb Space Telescope mission. The placing of the observatory at L2 and long periods of autonomous operations mean that observations can be split over several time periods or 'visits'. Data are processed through standard science data reduction pipelines after arriving at the Space Telescope Science Institute (STScI). We describe how data from visits and pipeline processing lead to the data products that are to be stored in the archives. Most observations will require a number of exposures; we discuss the data associations that will formulate the highest level of pipeline products that will be available in the MAST archive for JWST. The JWST observatory has numerous spectroscopic modes, including integral field units and multiple object spectra which will distinguish it from the Hubble Space Telescope archive. We describe the expected data products and services. Finally, we discuss the links to data analysis software and archive products available for user reprocessing.
