  1. Large Synoptic Survey Telescope News since the February update Astronomy & Astrophysics Advisory Committee Telecon May 2012 Fred Borcherding/Nigel Sharp/Kathy Turner

  2. Budget and Schedule • NSF MPS/AST • $7.5M for LSST Design & Development in FY13 request • Proposal for FY13-FY15 continued D&D is in hand • DOE Office of Science/HEP • $10M Major Item of Equipment request in FY13 • Re-alignment of NSF/DOE schedules/budgets • For MREFC start in Q4 of FY 2014, completion of major construction deliverables would occur in 2019 • Survey begins October 2021 after two-year commissioning • Total construction cost (including contingency, then-year dollars) of $457M NSF, $160M DOE, $39M private

  3. MREFC Construction Funding (taken from FY 13 request)

  4. NSF MREFC panel report • “[U]nanimous recommendation of LSST as the highest priority major science facility opportunity that should be the next project to receive NSF MREFC funds for construction.” • Conditional on completion of • NSF-DOE joint systems engineering review • Signed letter of intent with DOE, addressing individual agency and joint interagency responsibilities, in anticipation of completion of a detailed NSF-DOE Memorandum of Understanding

  5. Recommended additional reviews • Separate cost estimation review – May 15/16 • Total Project Cost (TPC) and methodology of PMCS were endorsed by NSF PDR in September 2011 • Three external scrutineers to validate cost update (<$28M) and to consider cost and contingency substantiation • Detailed Systems Engineering and NSF-DOE Interfaces Review – May 30-June 1 • Interfaces between telescope (NSF portion) and camera (DOE portion) to ensure that all scope is accounted for • Flow-through to science impact of any shortfalls in meeting detailed specifications

  6. Interagency agreements • Statement of Intent between DOE and NSF signed 4/16/2012 • Signed by Dr Brinkman and Dr Marrett • MOU to enter formal clearance process in May 2012 • Declares scope of responsibilities, NSF as lead agency • “… the two agencies together will support the integration, commissioning, and subsequent ten-year prime mission operations of the integrated LSST systems” • Sent to OSTP/OMB with signed cover letter • MOU: advanced draft in iteration • Common baseline for scope, budget, schedule, and risk • Agency oversight roles and responsibilities • Integrated project office • Development of mutually agreed data policy

  7. LSST data policy • LSST Data Policy is still in development. • Data levels: • Level 1 – raw data off telescope • Level 2 – initial processing • Level 3 – derived info – catalogs with parameters, shapes, colors • Project is investigating financial contributions towards annual operations cost in return for data access, as well as other possible interests in joining the experiment, under terms yet to be negotiated. • It is not likely that there will be unrestricted rights to the data: there will be access levels. It is also likely that there will not be redistribution rights (e.g. to use for any purpose or project you like). • Initial position: • Transients – free, open, immediate access • Some level of raw data will be immediately accessible • Annual release of catalogs of Level 3 data • NSF-AST and DOE-HEP reserve approval rights over all agreements.
