  1. The Project Data Management Plan David Band – GSSC

  2. Current Status • I have been maintaining the PDMP for 3 years; it has been in its current form for ~2 years. • The PDMP is informed by: • The mission AO • The proposals for the two instrument teams • The Science Requirements Document • The Mission System Specification • The Ground System Operations Concept Document • The PDMP is a Project document—433-PLAN-0009—but it has not been put under Configuration Management yet. However, it has been considered mature enough to be presented at major Project reviews.

  3. Revisions • I have been updating the PDMP based on: • Evolution of the ground system • Decisions regarding data rights • The most recent revision was last month—the resulting draft is on the GSSC website at http://glast.gsfc.nasa.gov/ssc/dev/current_documents/ • The drafts have been reviewed frequently by: • Project Scientist and his deputies • NASA Program Scientist and others at NASA HQ • The Science Working Group • The instrument teams • GSSC staff • Project staff, especially from the ground system

  4. What This PDMP Is Not • The GLAST PDMP is NOT the Interface Control Document (ICD) for data products exchanged between ground system elements. The data product tables are only for information. • Operations data products (e.g., commands, timelines)—ICD developed by MOC personnel. Fairly well developed. • Science data products (e.g., LAT and GBM event lists)—ICD developed by GSSC (posted on http://glast.gsfc.nasa.gov/ssc/dev/current_documents/). • Mature content definition for almost all data products • FITS formats defined for most. Some are standard OGIP files, others have been shown to OGIP FITS committee • This PDMP is not the controlling description of the ground system, of the operation plans, etc.

  5. What This PDMP Is • The GLAST PDMP describes the flow of data from the spacecraft until it is finally archived in the HEASARC at the end of the mission. • As such, this PDMP is the controlling statement of the GLAST data rights policies. • Other that the data rights policies, is the PDMP ‘obvious?’ NO! • Telemetry through TDRSS and not ground stations • Level 1 data processing by the instrument teams, not a science operations facility tied to the MOC or science center • Commands flow from instrument teams to the MOC through the GSSC (which evaluates impact on science observations) • The GSSC is tied to the HEASARC; most science data products are served directly or indirectly through Browse interface
