TIM JENNESS

D.M. Subsystem Requirements

• LSE-61 (DM SR) flows down from LSE-30 (Observatory System Specifications) and

Data Products Definition Document (DPDD/LSE-163).

• DPDD is a “source of truth” for DM but included claims that were not part of the DM

requirements (but in some cases were part of LDM-151).

• DPDD has been audited:
• Statements in DPDD now linked to specific requirement in DMSR.
• New requirements created when statements in DPDD had no corresponding

requirement.
