The Online DataFlow Subsystem of the BaBar Detector

This page contains released documents and presentations pertaining to the BaBar Online DataFlow (ODF) Subsystem. The term DataFlow System (DFS) is also commonly used to refer to this system. ODF has both an Electronics component (the Fast Control and Timing System Modules and the Read-Out Module), and a Computing component (the DataFlow software and the integration with the rest of the Online). Links and information on other BaBar Online or Electronics topics can be located elsewhere in the documentation hierarchy.
