  1. Science Operations UpdateNGAO - Meeting 11 D. Le Mignant, E. McGrath & C. Max W. M. Keck Observatory 11/05/2007

  2. Talking Points • Update to the picture • Science cases update • The path to release 2 of SCRD • SRD update • version 1.15 available for comments • Science Ops WSPS • The on-going: Pre-observing interfaces: • The guide star tool • The equivocal • Discussion / comments

  3. System Design Approach System Engineering Science Operations Performance budget Trade Studies 3.4: Science Ops Functional Rqts Observing Efficiency Budget Observing Models TS: KAON 476 Main Drivers & Risk Areas • WSPSs • Pre-observing interfaces Observing Timeline Rationales for Functional and Performance Requirements SRD v1.15 Observatory Rqts Science Operations Observing Scenarios SCRD v. 2 progress status Science Requirements

  4. Priorities from last meeting (09/17) • SCRD • Include/retrofit observing scenarios • “All-in” science simulations for SCRD • E.g., Requirements for PSF reconstruction • SRD from the operations perspective • Science ops requirements • Based on ?? • Observatory overall requirements • Based on ?? • Observing efficiency performance budget • See Science Ops page • NGS backup science TS? • FRD for science operations • WBS 3.1.3.3.6 • Science operations plan • WBS 3.4 • WBS 3.2

  5. Science Cases Update • Claire, Liz and David produced a completion status table for the science cases (Key science drivers and science drivers): • Linked here • Rationale: • Manage the simulations and edits for each science case • Case / case -> small team for each science case • Expected outcome: release 2 of SCRD • For each science case • Status of SCRD & SRD tables and text • Status of observing scenarios • Status of simulation (AO and science) and new requirements • Need to identify SC Volunteers (we don’t pay them!) • What’s next: • Find and work with the volunteers case by case. (twice a month meetings, etc) • Time/effort allocation? • Process already started for Asteroids (KSD #1)

  6. SRD v1.15 • Included changes up to 1.14 • Changes to section 6.1 and 6.2, then posted on the NGAO TWiki pages: linked here • Included science operations in section 6.1.4, • Requirement summary tables 19-21 • Updated section 6.2 Observatory Requirements • Added (moved) telescope and dome environment requirements • Added Observatory Operational requirements • Any volunteer to review the changes and iterate?

  7. On-going WSPS • Science operations: the on-going • WBS 3.4.1.1: Pre-observing interfaces • AO Guide Star Interfaces • Science Observations Simulation Tools • Soon to start: • WBS 3.4.1.2: Observing interfaces • Acquisition • Observing Sequences • Instrument, AO & Telescope Observer Interfaces • Science Data Quality Monitoring • TBD: FRD for science operations • WBS 3.1.3.3.6

  8. AO Guide Star Interfaces

  9. Science Observations Simulation tools • Requirements on Simulation Tools have to be defined and include similar challenges than for PSF reconstruction: • How to measure the quality of simulations • SR, EE, FWHM of peak and halo • PSF radial fit • Speckle intensity and distribution • Deconvolution residuals • ? • What is the experience of GPI and others • Coordination of the effort with the IWG • How much can anticipate an instrument interface design? • Requirements?

  10. 3.4.2.1 Operations Architecture • Click here • WSPS not agree and equivocal • TBD coordination work with 3.2 3.4.2.2 Operations Optimization • Click here • WSPS not agree and equivocal • TBD coordination work with 3.2

  11. Discussion / Comments • Priority list • More effort on SCRD/SRD than FRD for operations • Pre-observing Interfaces on-going • Observing timeline / observing scenarios • Operations Architecture.. (not before December) • Iterations between science requirements and system design. • Our plan includes iterations between the SCRD and the AO system design. • Simultaneously with completing SCRD v2.0, we need to be working with Rich to refine his spreadsheet calculations of the relevant wavefront errors; with Chris and scientists to simulate the relevant AO performance for analysis by the scientists; then use simulations to translate science requirements to AO system requirements. • We hadn't expected SCRD v. 2.0 to take as long as it has taken. • Requirements tables from SRD were a very useful approach, and have clarified what are the key questions that need further work. • Some of these have been addressed, others are in progress • Hard to get senior scientists to do substantive work; younger generation has been more useful. • SCRD v. 2.0 completion status will be posted and updated. • Any questions?
