| Abstract: |
Astronomical data analysis systems, especially in space projects, usually have a very long expected lifetime after the relatively short operational project phase when developer resources are available. Therefore these software projects need to take measures to make sure astronomers can continue to run the necessary mission-specific data analysis tools. Computing hardware available to astronomers tends to evolve substantially over timescales of about 10 years. Data access and data reduction of raw data are usually highly dependent on the availability of a data product archive and of the processing software. There are a number of issues that might jeopardize the legacy availability of astronomical software systems. |
