Detail tests with ComCam for Early System AI&T (same 2)
Detail Science Camera tests for Full System AI&T (3)
Non-MIE Camera supplied hardware design, costing and BOEs (10 in parallel with above)
This is list from Chuck with number of weeks allotted to get it done in parenthesis

Bold is fairly well covered in I&T scope (but full team feedback needed)
Regular is maybe covered at some level by I&T and SE
Faint is covered no where in MIE as far as I can tell.

I show this quickly to remind people we are a big team and I need input from everyone. (I’ve started collecting info but have a lot more to do).

DAQ
L1-L2 Lens Assembly
Camera Control System

8. I&T -> Commissioning
I&T planning summarized:
LCA-40 Integration and Test Plan
LCA-283 Camera Verification Test Plan
LCA Survey and Alignment Plan
Documentation
eTraveler summaries, NCRs, as built docs, etc
Characteristics Data Delivered with the Camera
Information delivered to Data Management
Iterated several times and under change control, LSE-130
Details of vendor test data will be added as they are determined
Includes:
As-built position information from I&T
FEA distortion models
Sensor and optics characteristics (from test plans)
Filter and lens vendor test results
Optical model as-built inputs/updates to support integrated observatory modeling
Shutter motion profiles and shadowing model as a function of position measurements
Thermal model to interpolate temperature measurements
Configuration

9. Summary of inputs from camera team
Camera Management
Need to clearly understand colors of money ($$$) and properly manage boundaries. Create BOEs and resource loaded schedule.
Camera Systems Engineering
While camera fully verified at camera preship review questions will (almost certainly) come up during commissioning
What role is needed from camera SE during commissioning?
eTraveler transfer of knowledge? NCR handling?
Sensors/Science RAFTs
Transfer of fixtures from BNL to LSST?
Transfer/maintenance of knowledge?
On sky sensor data/performance evaluation.
Handling colors of money is very important to get right.

10. Summary of inputs from camera team
Corner RAFT*
Like SR only digital access at commissioning
Wavefront data and guide data!
Optics
All the filters will be fully characterized by the vendor by direct measurements on the actual optics across the entire aperture. r-filter, at least, also well tested at SLAC.
Float indicates all filters tested at SLAC but possible summit work needed (CCOB thin beam at summit is currently planned)
Optics handling expertise at LLNL needs transfer to camera I&T and commissioning (not just a piece of paper with procedure)
L3 integrated at delivery
L1/L2 assembly (likely) reintegrated and aligned in Chile

11. Summary of inputs from camera team
Shutter
Well tested at I&T prior to delivery
Shutter swaps at summit during commissioning?
On sky performance input/feedback
First shutter refurbish as part of commissioning?
Filter exchange*
Autochanger swaps at summit during commissioning?
On sky/telescope input/feedback
First autochanger refurbish as part of commissioning?
Cryostat/refrigeration*
Pathfinders during ComCam
Commissioning systems (2) at summit

12. Summary of inputs from camera team
CCS
Pathfinders
Need CCS prior to ComCam
More than any subsystem (I think) CCS will be asked to add many things not in their original list of requirements. Significant manpower needs during commissioning.
Calibration telescope ?
DAQ
Need DAQ prior to ComCam
Calibration telescope?
Network issues/boundaries (summit, summit to base, etc)

13. Summary of verbal inputs from camera team
I&T
I&T ends with camera ready to ship
I&T has scope ( ) to design, build or design/build shipping container for camera
But not all the other things that need to ship.
Nominal plan has been to reuse the L1/L2 shipping container from Optics/Ball Aerospace and ship rest of camera as one piece
Filters back in their shipping containers
Commissioning must cover shipping costs
All of camera I&T goes to Chile
Fixtures and a-frame crane for clean room in I&T budget
Alumalift, RAFT level test stands, computers
Everything else? (tools, clean room gear, etc) are not.

14. LSST Commissioning: Camera Time FrameS

15. Time Frames: Camera Perspective

“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 lead (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.”
What did I miss?

19. LSST Commissioning: Logistics and Existing Plans

20. 9 3?
Logistics of shipping I&T fixtures prior to camera indicates that some fixtures arrive with camera thus requiring time to install fixture before reassembling camera.
