This chapter is intended to provide a framework for the configuration of the SOHO Experiment Operations Facility (EOF). A more complete description of requirements for the NASA-supplied elements of the EOF can be found in the SOHO EOF Core System Functional Requirements Document (ECS FRD; edition of April 1992 and subsequent revisions). Data exchange and command interfaces are described in detail in the ECS-Experimenter Interface Control Document (January 1994 and subsequent revisions).
