Goals:
   * Introduce team structure and responsibilities
   * Review System Requirements Document (Release 1)
   * Review key drivers for each of the NGAO performance and efficiency budgets
   * Review recent trade studies
   * Review Keck Interferometer requirements (N.B. these are _not_ (yet) NGAO requirements imposed by KI)
   * Review instrumentation study strategy for NGAO system design phase
  
Agenda:
   *  8:00 am Refreshments
   *  8:30 am Welcome and Team Introductions (*All*)
   *  9:00 am Management Report (*Wizinowich*) [[%ATTACHURL%/NGAO_meeting_%232_1106.ppt][Management Report.ppt]]
      * Review study overall progress, progress against milestones, and summary financial situation
   *  9:30 am Science Requirements Document (Release 1) (*Max*) [[%ATTACHURL%/NGAO_SRD_Release1_v3-print.pdf][NGAO_SRD_Release1_v3-print.pdf]] [[%ATTACHURL%/Max_ScienceRequirements_v1a.ppt][Max_ScienceRequirements_v1a.ppt]] [[%ATTACHURL%/Max_ScienceRequirements_v1.ppt][Max_ScienceRequirements_v1.ppt]] [[%ATTACHURL%/PerformanceRequirements_v2.xls][PerformanceRequirements_v2.xls]]
      * From the SD SEMP: The SRD describes the new system in terms of the needed scientific and technical performance.  The document also expresses specific requirements for implementation or design where those requirements are essential to satisfactory integration and interoperation of the new system with other observatory systems.  
      * Review _changes_ to science requirements contained in SRD (Release 1) compared to June NGAO proposal
      * Discuss science / engineering team interactions
   * 10:30 am *Break*
   * 10:45 am Key Performance Drivers (*Dekany*)  [[%ATTACHURL%/Perf_budget_dev_rgd.ppt][Perf_budget_dev_rgd.ppt]]  [[%ATTACHURL%/Perf_budget_dev_rgd.pdf][(.pdf)]]
      * Review the NGAO Required Observing Modes
      * Review the key architecture and technology drivers for each of the 6 Performance and 2 Efficiency Budgets
            * Astrometric Accuracy (*Cameron*)
            * Background and Sensitivity (*Bouchez*)
            * Encircled Energy (*Gavel*)
            * High-Contrast (*Macintosh*)
            * Photometric Precision (*Britton*)
            * Polarimetric Precision (*Ireland*)
            * Wavefront Error (*Dekany*)
            * Observing Efficiency (*LeMignant*)
            * Observing Uptime (*Johansson*) [[%ATTACHURL%/uptime.ppt][Uptime budget presentation]]
   * 12:15 pm *Box Lunch (provided)*
   *  1:00 pm Trade Study Report: LGS Asterism Geometry and Size (*Flicker*) [[%ATTACHURL%/TS-tomo.pdf][TS-tomo.pdf]]
      * From the WBS Dictionary:  Find the simplest LGS asterism geometry meeting the performance budget goals (e.g. quincunx, ring, 1+triangle, or hex) and the asterism radii.  Consider optimization of the Strehl of the tip/tilt stars and the resultant sky coverage as well.  Complete when LGS asterism, HO WFS, and LO WFS requirements have been documented.
   *  1:30 pm Trade Study Report: Fixed vs. Variable LGS Asterism (*Velur*) [[%ATTACHURL%/NGAO_m2_VFA_final.ppt][NGAO_m2_VFA_final.ppt]]
      * From the WBS DIctionary:  Consider the cost/benefit of continually varying the LGS asterism radius vs. a fixed number of radii (e.g. 5", 25", 50").  Complete when LGS asterism requirements have been documented.
   *  2:00 pm Keck Interferometry Requirements (*Neyman*) [[%ATTACHURL%/KI_req_NGAO_crn.ppt][KI_req_NGAO_crn.ppt]]
      * Review the KI requirements on delivered wavefront, including wavefront error and polarization
   *  2:30 pm NGAO Instrument Study Strategy (*Adkins*) [[%ATTACHURL%/NGAO_Instrumentation_Version_1.ppt][NGAO Instrumentation.ppt]] [[%ATTACHURL%/The_NGAO_Instruments_Working_Group_revised.pdf][NGAO Instruments Working Group.pdf]]
      * Review the strategy, scope, organization, and expectations for instrument "proposal-level" development within the NGAO system design phase
      * Discuss science /engineering team interactions
      * Review schedule for initial NGAO instrument concepts (proposed:)
         * Near-infrared Imager
         * Visible Imager
         * Deployable Near-Infrared IFU Spectrograph
      * Review scope of upcoming Trade Study: Science Instrument Reuse
   * 3:45 *Break*
   * 4:00 Discussion: Upcoming tasks and milestones (*Wizinowich*) [[%ATTACHURL%/filename][.ppt]]
   * 4:30 General Discussion (*All*)
   * 5:30 Adjourn

   * Evening NGAO Dinner in Old Town Pasadena (6:30p)
      * Akbar Cuisine of India ($20) (_Wizinowich, Neyman, Dekany, Moore_)
      * Gaucho Grill (Argentinian) ($20) (_vote here_)
      * Il Fornaio (Italian) ($30) (_vote here_)
      * Twin Palms (Californian) ($40) (_vote here_)
