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-1 a 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 HMI Team Meeting – January 26 -27, 2005 Page 2
