3 Science Operations during the PD phase Narrative WBS 3.2 Requirements –WBS 3.2.1: Observing Operations Concept Document (OOCD) “Example observations”, including simulations of quantitative science output from NGAO + science instrument Uses cases, leading to operations sequences and science tools WBS 3.4 System architecture –WBS 3.4.4: NGAO Sequences Definitions Document (SDD) WBS 3.6 Science Ops Tools Design –WBS Multi-system Command Sequencer (MCS) –WBS User Interfaces –WBS Pre and post-observing science support tools –WBS Data server WBS 3.9 Operations Transitions –WBS Ops Plans –WBS Ops Handover

8 Science Operations during the PD phase Work in progress… Plan the deliverables: Outline/standard for the document Plan for release(s) and content update Lead person per document / section How to include (realistic) science instruments for quantitative estimates for the example observations Phase the effort (under the assumption there will be a learning curve on the science instruments)…

9 Priorities HIGH… OOCD Outline for release 1: Get buy-in and include suggestions / comments How do we include a case for the wide fov science? (assumptions, assumptions…) Sequences Definitions Document Outline and start of release 1 [Not a perfect flow-down..] Sci ops architecture Release 1 for system infrastructure (MCS)

10 Priorities low… Science operations support tools Release 1 in support of working on observing scenarios (i.e., narrow-field science:OSIRIS, VIS/NIR-IMGR) Keep it descriptive for d-IFS for instance?? User Interface (release 1 - tbd) Observing sequences control Science observing sequences Awaiting progress on science instrument [e.g., fine centering with coronagraph] Troubleshooting & alarm handling? Operations Transitions (100h for DLM) Outline for document (~ 20h or less)

11 Comments and discussion Questions about priorities? High and low “Build to cost paradigm”, can be seen as: Opportunity to deliver an integrated science machine Driven by the science instruments requirements:  Review science case to cost-benefit  Include design/build of science instruments  Focus on science instruments rather than details on science operations and observing sequences, e.g, who cares about 5% observing efficiency when you don’t know whether there will be 0, 3 or 6 d-IFS Outstanding science instruments are key to AO success!
