9. Scope & Definitions of the Commissioning Plan

10. Commissioning Scope
The LSST Commissioning Plan covers the final system level assembly, integration and testing (AI&T) of the three primary subsystems – Telescope, Camera and Data Management – plus the infrastructure supporting EPO and Headquarters operations into the LSST Observatory System. Commissioning includes DOE “early operations” funded (non-MIE) activities.

11. Commissioning Scope
The Commissioning Plan is derived from the following inputs:
System level verification plan per LSE-160, including the SysML based verification event sequences and logic;
Subsystem assembly, integration and test plans (T&S: LTS-104; Camera: LCA- 40; DM: ???) with subsystem requirements identified that can only be verified once commissioning starts;
Scientifically motivated system performance characterization; and
Technical optimization of system operations.

12. Commissioning Definitions
A useful guiding principle for commissioning boundary definition follows: An activity is considered part of commissioning when it involves a “delivered” component from one of the subsystem “touching” that of one of the other subsystems.

13. Commissioning Definitions
Commissioning activities involving Data Management starts when components receive “real data” from one of the principal sources, including the Auxiliary telescope/instrument, ComCam or the full Science Camera.
First calibration data from Auxiliary Telescope: August 2018
First on-sky and calibration images with ComCam: September 2019
Sustained observing with ComCam: February 2020
Images from Camera re-verification at Summit Facility: June 2020
First on-sky and calibration data from Camera+Telescope: October 2020
Sustained scheduler driven observing with Camera+Telescope: January 2021
Start Science Verification mini-Surveys: April 2021

14. Commissioning Definitions
Commissioning activities involving the Camera begins with shipping from SLAC to Chile and re-verification on the Cerro Pachon summit. Re- verification activities of the Camera will be led by DOE personnel, but coordinated through the Commissioning team and plan. These activities are currently scheduled to start February 14, 2020 with a Camera Pre-Ship Acceptance review at SLAC.

15. Commissioning Definitions
Significant commissioning activities involving the Telescope & Site starts with the arrival of ComCam in Chile leading to the beginning of Phase 1, Early System AI&T. These activities are currently scheduled to start April, when ComCam is delivered to the Summit Facility. Note: The auxiliary telescope is scheduled to begin observations in August 2018.

16. Commissioning Phases
Pre-Commissioning - Test procedure definition - Test analysis script development using the LSST code base - Procedure & script validation with simulation tools - Special hardware/software development
Phase1: Early System AI&T with ComCam - early interface testing - telescope alignment and AOS control - subscale DM pipeline testing
Phase II: Full System AI&T with Science Camera - camera-telescope integration, alignment & AOS control - full scale DM pipeline testing
Phase III: Science Verification - Operations readiness with mini-Surveys and Data Releases

17. Plan Status: Phase I
A single raft camera operating as a surrogate of the full science camera. Utilizes as many Camera system interfaces as possible:
CCS-OCS: Command/Control
SDS-DM: Image data delivery
WDS-TCS: Wavefront sensing
GDS-TCS: Guiding
Early Camera refrigeration testing
Early interface testing and optical alignment with active optics control
Early testing of science pipelines
Conceptual layout of ComCam with Camera surrogate mass integrated to rotator interface and telescope integrating structure.
Detailed design now underway.

18. Full scale science processing and algorithm testing
Plan Status: Phase II
Camera integration, calibration and full field optical alignment with AOS control
Scheduler testing & optimization
Full scale science processing and algorithm testing
Data Management integration focus includes:
Instrument signature removal calibration and verification
Full scale calibration products production
Full scale Level 1 alert production testing
Camera-Telescope integration focus includes:
Physical installation and basic functional checkout
Final calibration and verification of active optics look-up tables and optical feedback
Integrated system requirements verification (OSS)
OCS sequencing & functional interactions with scheduler driven observing

19. Full scale science pipeline processing
Plan Status: Phase III
Science verification focuses on characterizing the survey data performance properties defined in the LSR/SRD.
Verification matrix filled in with compliance and characterization data.
ORR mini-Surveys
Full scale science pipeline processing
Example sky coverage from a 30-day mini-Survey with a mean visit density of 6 visits per unit area.

20. Work Plan for getting to ComPDR

21. Elements of the re-plan
Clearly defined management structure and lines of responsibilities/authority
An integrated (DOE+NSF) commissioning activity schedule resource loaded by location and skill category (individuals identified where possible).  This schedule will also include early preparatory work. The Commissioning planning structure will be updated to include:
Data Management components - infrastructure, services and payloads (pipelines and databases)
Education and Public Outreach deliverables – data center and services
Location specific activities for main LSST facilities
Budget and staffing profile supported by DOE Early Operations Funding

22. Elements of the re-plan
Re-baseline MREFC plan to include early preparatory work
Requirements for additional tools (hardware and software) needed by the Commissioning plan
Update required pre-conditions for each subsystem prior to entering commissioning
