JSOC SDP Scope

• The HMI/AIA Joint SOC consists of two parts
• Science Data Processing at Stanford
• Science Instrument Operations at LMSAL
• JSOC SDP includes
• HMI and AIA Telemetry Data capture (from DDS) and
  archive
• HMI and AIA Level-0 processing and archive
• HMI processing through to level-2 with archiving
  of end products
• AIA processing through level-1a with online
  storage
• Data export of the above and other HMI and AIA
  products as needed
• JSOC SDP does not include other Stanford tasks
  such as
• HMI science analysis beyond level-2 products
• HMI and AIA EPO
• HMI Co-I science support
• JSOC SDP does not include other LMSAL tasks such
  as
• AIA level-1 and level-2 processing
• AIA science analysis beyond level-2 products
• AIA Co-I science support
