  14. Position of SET in SXC-project Spectrum-X Calorimeter SET: PA/QA Electrical Mechanical Thermal Software AIV Telescope Detector Ground segment Spacecraft SXC system overview

  15. System engineering • The subsystem teams are responsible for their own System Engineering, PA issues, configuration control etc. • The SXC-system engineering team will support subsystem reviews at best-effort base. • The SXC-system engineering will control interfaces and budgets external to the subsystems.
