LSST Commissioning: FY18 Planning Chuck F Claver LSST System Scientist & Commissioning Lead Monday, August 14, 2017

Discussion Topics Scope of “Commissioning” Planning for “CD-2 like Review” – February 2018 Planning beyond reviews

Commissioning answers three basic questions Did we build the thing we said we were going to build? Verification Does the thing we built do what we want / expect it to do? Validation Do we understand how and why the thing we built works the way it does? Characterization LSST2017 - Tucson, AZ - August 14 - 18, 2017

What is LSST Commissioning? It includes System Integration & Test – Telescope + Camera + DMS + EPO It includes system level verification of hardware & software It includes validation of the science products It includes characterizing the system as it is being built It includes characterizing the final as-built system … LSST Commissioning starts now LSST2017 - Tucson, AZ - August 14 - 18, 2017

Revised Data Delivery Schedule Data Production Milestone Start Date First calibration data from Auxiliary Telescope November 2018 First on-sky and calibration images with ComCam May 2020 Images from Camera re-verification at Summit Facility July 2020 Sustained observing with ComCam August 2020 First on-sky and calibration data from Camera+Telescope February 2021 Sustained scheduler driven observing with Camera+Telescope April 2021 Start Science Verification mini-Surveys June 2021 LSST2017 - Tucson, AZ - August 14 - 18, 2017

Planning for a “CD-2 like” Review Why yet another review? We are asking DOE for new money - $15.3M MREFC portion is estimated at - $21M Review baseline for both DOE & MREFC commissioning effort When will this review occur? Planning is focused on late February 2018 LSST2017 - Tucson, AZ - August 14 - 18, 2017

Review preparation timeline Working backwards… February (late) 2018: “CD-2 Like” DOE/NSF agency review January (late) 2018: Director’s review December (late) 2017 – mid-January 2018: Holidays + AAS meeting December 15, 2017: Materials needed for review are complete December 1, 2017: Plan details, schedule, budget and BOEs complete November/December 2017: Commissioning Workshop w/external participation October 31, 2017: Subsystem verification plans completed October 15, 2017: Subsystem verification matrices complete August, 2017 – December, 2017: Updates to the LSST Commissioning Plan – LSE-79 August, 2017: LSST 2017 – You Are Hear Commissioning Plan Document LSE-79 v4.6: http://ls.st/5gn LSST2017 - Tucson, AZ - August 14 - 18, 2017

What is needed for the review? Refine plan details to include: Add parallel activities for early testing and subsystem characterization Schedule explicit activities for daytime versus nighttime Expand details for the verification / validation of the science pipelines Observational procedures needed to support nighttime activities Update resource loading of the plan to support budget and schedule Develop and document BOEs for all activities LSST2017 - Tucson, AZ - August 14 - 18, 2017

What is a Basis of Estimate for an Activity? Description of Activity: Required initial conditions and inputs Expected outcome and end state Steps needed to go from start to end Allocated system verification events Activity Processes: Processes needed by each step Planned tests/analyses Observations/data needed Safety & Hazard Assessment: Critical lifts Specific hazards to activity Determination of Resource Estimates: Critical domain specific personnel Supporting personnel Time estimates for personnel Non-labor resources Special tooling Commissioning Confluence Pages: http://ls.st/3ge LSST2017 - Tucson, AZ - August 14 - 18, 2017

Who is needed to prepare for the review? PMO/PSE Support: Chuck Claver Brian Selvy Keith Bechtol Andy Connolly Bo Xin Brian Stalder Peter Yoachim Scott Daniels + others Camera Support: Kevin Reil Steve Ritz Vincent Riot Travis Lange Margaux Lopez Martin Nordby + others? Telescope & Site Support: Sandrine Thomas Bill Gressler Patrick Ingraham Jacques Sebag Doug Neill Francisco Delgado + others? DM Support: Simon Krughoff Wil O’Mulane Robert Lupton EPO Support: Ben Emmons LSST2017 - Tucson, AZ - August 14 - 18, 2017

How are we being organized? Systems Engineering & Commissioning Systems Scientist SE Manager Science Validation Team Core Integration Team Technical Coordination Team System Verification Team Brian Selvy Kathryn Wesson Michael Reuter + others… Keith Bechtol Andy Connolly Simon Krughoff Peter Yoachim Scott Daniels + others… Chuck Claver Kevin Reil Bo Xin Brian Stalder Sandrine Thomas Patrick Ingraham Travis Lange Margaux Lopez + others… TBD LSST2017 - Tucson, AZ - August 14 - 18, 2017

What is needed in FY18 beyond the review? Tool development Work with DM Manager and SQUaRE team to develop “bootcamps” for using the LSST Science Platform as a commissioning analysis tool Work with DM SQUaRE team to leverage SQUASH to support metric tracking during system verification and commissioning Validate tools with prototype commissioning procedures tested with legacy and/or simulated data JIRA based ticketing and tracking tool(s) LSST2017 - Tucson, AZ - August 14 - 18, 2017
