| Abstract: |
The California Institute of Technology was selected as the home for the SIRTF Science Center (SSC). The SSC is responsible for evaluating and selecting observing proposals, providing technical support to the science community, performing mission planning and science observation scheduling activities, instrument calibration during operations and instrument health monitoring, production of and access to archival quality data products, and management of science research grants. The SSC is responsible for design, development, and operation of the Science Operations System (SOS) which will support the functions assigned to the SSC by NASA. The SSC generates the standard science products by providing data reduction infrastructure services. The data reduction infrastructure is designed to handle both event-driven and batch requests. There is a significant reprocessing step which is nominally handled as a batch request while data arriving from the Mission Operations Center result in an event-driven request. Processing in this system is distributed while data management is centralized via a data management system. This paper will describe the development process, the top-level infrastructure architecture, the current implementation, and most importantly, the lessons learned from the development of the SSC data reduction infrastructure. Of particular interest will be the description of the downlink processing as a cooperating, interoperable component of SSC Science Operations System. |
