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)…
8
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)
9
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)

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!
