OPUS is a software system that was developed to process incoming data in a pipeline through modular software elements. Users could control individual elements, tailor the software to handle diverse types of data (astronomical, genomic, other experimental data), and run multiple processes to maximize efficiency.
OPUS was originally developed to handle and manage data from the Hubble Space Telescope and subsequently was used for a variety of astronomical and other types of science data. A description of OPUS is available in the Bibliography, but STScI no longer actively supports OPUS. STScI is now studying a number of processing options for the James Webb Telescope.
