Pipelines process the images to produce catalogs, which are then made accessible to the community via open interfaces in a Virtual Observatory model. Since new data is being collected nightly throughout the 10-year duration of Rubin Observatory's Legacy Survey of Space and Time (LSST), and scientific algorithms will evolve during this time frame, significant re-processing will occur. This must be taken into account in sizing Rubin Observatory technology resources and making the Rubin Observatory middleware easily extendable.

The pipelines can be categorized as "near real-time" or "static," depending on how stringent the associated latency and throughput deadlines are. Examples of near real-time pipelines include data quality assessments for providing feedback to telescope operations, instrument calibration processing, and time-domain/transient science analysis. These pipelines execute at the mountain/base facility in order to avoid the latency associated with long-haul transmission of the raw data. The static pipelines include deep image co-addition (stacking of paired exposures), weak lensing shear processing needed for dark energy and dark matter science, and object cataloging. These pipelines execute at the archive center, which also performs re-processing of the near real-time pipelines.

Financial support for Rubin Observatory comes from the National Science Foundation (NSF) through Cooperative Agreement No. 1258333, the Department of Energy (DOE) Office of Science under Contract No. DE-AC02-76SF00515, and private funding raised by the LSST Corporation. The NSF-funded Rubin Observatory Project Office for construction was established as an operating center under management of the Association of Universities for Research in Astronomy (AURA).  The DOE-funded effort to build the Rubin Observatory LSST Camera (LSSTCam) is managed by the SLAC National Accelerator Laboratory (SLAC).
The National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 to promote the progress of science. NSF supports basic research and people to create knowledge that transforms the future.
NSF and DOE will continue to support Rubin Observatory in its Operations phase. They will also provide support for scientific research with LSST data.
